What Is a Bikini? A Quick Overview
A bikini is a two-piece swimsuit with a top and a bottom designed for swimming, sunbathing, and beach activities. Simple enough on paper, but anyone who's actually gone shopping for one knows the reality: there are dozens of cuts, dozens of fabrics, and about a hundred ways to get it wrong if you don't know what you're looking for.
The bikini has been around since the late 1940s, but the sheer variety available today is something completely different from what existed even a decade ago. You have micro bikinis that barely exist, high waisted bikinis with a retro-glam aesthetic, triangle bikinis that feel effortlessly minimal, and thong bikinis that prioritize a seamless tan. Each style serves a different purpose, flatters a different figure, and speaks to a different personality.
This guide is built to cut through that noise. Whether you're heading to a resort pool, a rocky European beach, or a lazy Sunday afternoon in your backyard, you'll find exactly what you need here — and know where to go to get it.
The Most Popular Bikini Styles Explained
Knowing the difference between styles isn't just about aesthetics. It's about comfort, function, and making sure you're not adjusting your top every five minutes in the water.
Triangle Bikini
The triangle top is probably the most recognized bikini silhouette in the world. Two triangular panels of fabric tied behind the neck and at the back, leaving the sides of the chest and a lot of the back exposed. It's lightweight, minimal, and works beautifully for sunbathing because it leaves very few tan lines.
The downside? It’s not a heavy-duty support top. Women with larger busts often find triangle tops uncomfortable for anything active. For a detailed breakdown of how it stacks up against the string style, read our guide on string bikini vs triangle bikini.
String Bikini
String bikinis look similar to triangles but emphasize even more adjustability — the ties on the sides of the bottoms and the ties on the top mean you can customize exactly how the suit fits you. This is especially helpful if your top and bottom are different sizes (which, for most women, they are).
High Waisted Bikini
The high waisted bikini bottom sits at or above the natural waist, covering the lower abdomen and hip area. It’s had a major comeback over the last several years, and for good reason — it’s incredibly flattering on a wide range of body shapes, it provides more coverage without sacrificing style, and it pairs beautifully with both bandeau tops and underwire tops.
Our Women’s High Waist Bikini Swimsuit is one of our most popular styles for exactly these reasons. For a full comparison of how this style holds up against the thong cut, check out our high waisted bikini vs thong bikini guide.
Thong Bikini
The thong bottom is cut to expose the majority of the rear and sits high on the hips. It's popular for eliminating tan lines, for a streamlined beach look, and for the simple confidence of wearing something that demands you own it. It's not for everyone, but for those who love it, nothing else quite compares.
Brazilian Bikini
The Brazilian cut sits somewhere between a standard bikini bottom and a thong more coverage than a thong, less than a traditional bottom. It typically sits high on the hips and has moderate rear coverage. Our Women’s Brazilian Bikini Swimsuit Set and Women’s Brazilian Split Bikini Swimsuit are great examples of this style done well.

Micro Bikini
The micro bikini is exactly what it sounds like — minimal coverage, maximum confidence. It’s a style that’s less about swimming laps and more about a certain beach aesthetic. It requires confidence and works best in calm water settings or poolside lounging. Our full breakdown covers everything you’d want to know: What Is a Micro Bikini? Complete Style Guide.
How to Choose a Bikini for Your Body Type
Here's something that doesn't get said enough: every body type can wear every style. But certain cuts do tend to work more harmoniously with certain proportions — not because of any rule, but because of how fabric drapes, where emphasis falls, and how comfortable you'll actually feel wearing something.
Apple Body Shape (Wider Midsection)
If you carry weight in your midsection, high waisted bottoms are often a revelation. They smooth and support the abdomen area without squeezing. Pair them with a structured top — an underwire or a bandeau with side boning to create a balanced silhouette.
Our Women’s Floral Print Underwire Bikini works particularly well here, giving shape and lift while the high waist bottom creates proportion below.
Pear Body Shape (Wider Hips)
For pear-shaped figures, the goal is often to draw attention upward. Bold prints on the top, a push-up style, or embellished details at the neckline do this naturally. Keep the bottom simpler — solid colors, minimal hardware.
Hourglass Body Shape
Hourglass figures are well-suited to almost any cut, so this is really about personal preference. String bikinis and triangle tops work beautifully here because they highlight the waist without obscuring it. Brazilian cuts and thong bottoms emphasize the hip-to-waist ratio that this body shape naturally has.
Athletic / Straight Body Shape
Athletic builds often benefit from cuts that add the appearance of curves. Ruffled tops, push-up styles, and bandeau cuts create volume at the chest. Brazilian or hipster bottoms add volume at the hips and rear.
Full-Bust Figure
Support is the priority. Underwire tops, halter necks, and wider straps distribute weight properly and allow you to actually move without worrying. Our Women’s Floral Print Underwire Bikini is designed with this in mind it’s supportive without looking like it’s trying too hard.

Bikini Fabrics & What They Actually Mean for Fit
You can get two bikinis that look identical in photos and feel completely different on your body. Fabric is the reason.
- Nylon/Spandex blends are the most common in quality swimwear. They hold their shape in water, dry quickly, and stretch and recover well. The higher the spandex percentage (usually 15–20%), the more form-fitting and supportive the suit.
- Polyester is incredibly resistant to chlorine and UV damage. If you're a pool swimmer, polyester-based suits last significantly longer than nylon.
- Recycled fabrics (like ECONYL) perform similarly to virgin nylon with a much lower environmental footprint.
- Avoid cotton in swimwear unless it's lined. Cotton absorbs water, loses its shape, and fades quickly with sun and chlorine exposure.
Pro Tip: When checking fit, always sit down, bend over, and move your arms while trying on a bikini top. A top that looks great standing still but gaps at the chest when you move is a fit problem, not a style problem.
How to Style Your Bikini Beyond the Beach
A bikini is more versatile than most people give it credit for. With the right layering and accessories, bikini tops especially can carry into casual daywear effortlessly.
- Bikini top as a crop top: A structured triangle top or bandeau under a linen blazer or loose button-down shirt works as a beach-to-lunch outfit without changing. Add high-waisted shorts and slides.
- Layering for beach coverage: A sheer sarong tied at the waist, a kaftan, or a lightweight romper over your bikini is the classic beach cover-up solution.
- Accessorizing: Layered gold jewelry — necklaces, anklets, simple rings — elevates a bikini look instantly. Wide-brim hats are practical for sun protection and photograph beautifully.

Bikini Color & Print: What Works and What Doesn't
Color in swimwear isn't just aesthetic — it affects visibility in water, how quickly fabric shows wear, and how much heat it absorbs in direct sun.
- Black bikinis are perennial bestsellers for good reason. They’re slimming, they hide wear and fading better than any other color, and they’re infinitely versatile. Our Women’s Floral Print Underwire Bikini in dark colorways demonstrates how a classic base can still feel current with the right print detail.
- White bikinis look stunning but require more care they’re transparent when wet, and any makeup, self-tanner, or sunscreen will stain them quickly. White also tends to show the most aging from chlorine and sun. That said, there’s almost nothing more classic poolside. Read our full guide on white bikini outfit ideas for tips on making white work.
- Prints — florals, tropicals, abstract patterns — add personality. A bold floral on the top draws the eye upward; a busy print on the bottom adds volume at the hips.
- Solid colors are easier to mix-and-match. Start with two or three solid-color separates in complementary tones before adding prints.
Bikini Care: How to Make Yours Last Longer
A quality bikini is an investment. Here's how to protect it.
- Rinse immediately after use — especially after swimming in a pool. Chlorine degrades spandex fibers faster than almost anything else.
- Hand wash in cold water with a mild, fragrance-free soap or a swimwear-specific detergent. Machine washing puts unnecessary stress on the fibers and elastic.
- Never put a bikini in the dryer. High heat destroys spandex elasticity. One dryer cycle can age a swimsuit by months.
- Rotate suits if you swim regularly. Giving elastic time to recover between wears keeps its shape significantly longer.
- Sunscreen and self-tanner are among the most common causes of bikini staining. Apply sunscreen, let it absorb fully, then put your suit on.
Current Bikini Trends Worth Knowing
Swimwear trends move slower than fashion, which is actually good news — most of what's popular right now has staying power.
- Retro silhouettes are still strong. High waisted bottoms, underwire tops, and bandeau cuts continue to dominate.
- Texture and fabric detail — ribbed fabrics, ruching, and textured knits add visual interest without requiring a bold print.
- Minimalist aesthetics — clean lines, solid colors, minimal hardware, and simple cuts.
- Mix-and-match separates have become standard. Most women today buy tops and bottoms independently.
- Sustainable swimwear is growing. Recycled materials and ethical production are now a deciding factor for many shoppers.

How to Shop for a Bikini Online Without Getting It Wrong
Online swimwear shopping has a reputation problem — fit is hard to predict, photos are often misleading, and return policies vary wildly. Here's how to get it right.
- Know your measurements. Bust, underbust, waist, and hips. Use these against the brand's specific size chart, not generic sizing.
- Read reviews for fit information specifically. Reviews that mention cup size or strap length are more useful than aesthetic praise.
- Look at the fabric content. Higher spandex percentages (18–20%) mean more stretch and recovery.
- Check the return and exchange policy before you buy. At Happari, we want you to find a suit that actually works — contact us if you have fit questions before ordering.
- Order two sizes if you're between sizes. Keep the one that fits and return the other.
FAQ
What is the most flattering bikini style?
There’s no single answer it depends on your body shape and what you personally want to emphasize or minimize. High waisted bottoms are widely flattering for most figures. For tops, underwire styles provide the most support and shape. Our body type guide gives specific recommendations.
What's the difference between a string bikini and a triangle bikini?
Both are minimal styles, but a triangle top has fixed triangular fabric panels while a string bikini uses smaller triangles with more adjustable ties at multiple points. Read our full string bikini vs triangle bikini comparison.
How do I keep my bikini from fading?
Rinse immediately after use, hand wash in cold water, skip the dryer, and store out of direct sunlight. Chlorine is the biggest culprit — rinsing within minutes of leaving the pool makes a real difference.
Can I wear a bikini top as a regular top?
Absolutely. Triangle tops and bandeaus in particular work well under open shirts, blazers, or on their own with high-waisted shorts or trousers. Stick to structured tops for the most versatile crossover look.
What's the best bikini for a larger bust?
Underwire tops, halter necks, and styles with wider straps offer the most support. Avoid unlined triangle tops or bandeau styles without underwire for anything active. Our Women’s Floral Print Underwire Bikini is a strong option.
How do I know if my bikini fits correctly?
The top should sit flat against your chest with no gaping, the straps should be comfortable (not cutting in or falling off), and the bottoms should cover what you want them to cover without bunching or riding up when you walk.
Is a Brazilian bikini the same as a thong?
No. A Brazilian offers more rear coverage than a thong while still sitting high on the hips. A thong exposes almost all of the rear. See our thong bikini guide for more.
What bikini style is trending right now?
High waisted bottoms, ribbed textures, minimalist solid colors, and mix-and-match separates are all having a strong moment. Retro-inspired underwire tops continue to grow in popularity.
