How to Choose the Perfect Swimsuit: A Complete Style & Fit Guide

Swimsuit shopping at Sand Surf Co. hits different. Our team knows the brands, the cuts, and the fits — which ones run small, which ones you can size down in, and which styles look incredible on the hanger and even better in the water. And the fitting rooms? They're a vibe. You're supposed to enjoy this part.

With this many styles to choose from, a little direction goes a long way. This guide breaks down every swimsuit style we carry, what each one is actually for, and how to find the one that fits your body and the way you actually live at the beach.


Start With How You're Using It

Before you think about style, think about what you're actually doing in the swimsuit. This one question eliminates half the options immediately.

  • Lounging and socializing — Full style flexibility. Go for whatever you love the look of.
  • Active swimming or water sports — You want security. A sporty two-piece or one-piece keeps everything in place while you move.
  • Beach days with kids — Practicality matters. You’ll be in and out of the water constantly — you want something that stays put without constant adjusting.
  • A vacation where you want to look amazing — This is when you invest in something you genuinely love, even if it’s a little more delicate.

The Main Swimsuit Styles Explained

Triangle Bikini

The classic — and the style that never really goes out of fashion. A triangle top ties at the neck and back; bottoms are typically a brief or cheeky cut. Triangle bikinis are versatile, adjustable, and popular for a reason: you can fine-tune the fit, and they come in more print and color options than any other style. Cheeky coverage, big personality.

Best for: Sun tanning, beach days, anyone who wants maximum style flexibility with a flirty, feminine feel.

Bandeau Bikini

A strapless, tube-style top — clean, minimal, and perfect for eliminating tan lines and soaking up every bit of Florida sunshine. Modern bandeaus have serious structure: boning, underwire, and optional removable straps make them a legitimate all-day option. Kulani Kinis does this style especially well — the construction keeps everything in place without a second thought.

Best for: Anyone who hates strap tan lines; a sleek, effortless look that keeps things minimal without sacrificing support.

High-Waist Bikini

The high-waist bottom sits at or above the natural waist — more coverage on the bottom without losing the two-piece feel. It pairs well with virtually any top and has a timeless, slightly retro appeal that never really goes out of style.

Best for: Anyone who prefers a little more coverage on the bottom, or loves a vintage aesthetic with a modern print.

One-Piece

We’re selective about the one-pieces we carry — when we have one in the shop, it’s because it’s genuinely worth it. Think fashion-forward cuts with something interesting going on: a deep open back, a high-cut leg, or architectural detail that makes it the piece you plan your whole beach day around. This isn’t your everyday swim look — it’s a statement.

Best for: Anyone who wants one put-together swim look that does all the talking for them.

Rashguard & UV Swimwear

We’re in Florida — the sun is kind of the whole point. But on marathon beach days or long paddleboarding sessions, a rashguard or UV swim top lets you stay out longer without retreating under an umbrella. The options we carry are fitted and flattering, not the boxy swim shirts you remember from childhood.

Best for: All-day beach sessions and paddleboarding where you want to maximize your time in the sun.

A Note on Fit (The Part Most Guides Skip)

The single biggest factor in how a swimsuit looks and feels isn’t the style — it’s the fit. Here’s what to actually check:

  • In the bust: Cups should lay flat with no gaps, no spillage, no wrinkling. Pulling or caving inward means you need a different cup size or cut.
  • In the seat: Bottoms should sit without cutting in or sagging. Constant pulling or readjusting means the cut isn’t right for your shape.
  • In the torso (one-pieces): No pulling at the straps, no bunching, no sagging in the chest. The fit at the torso makes or breaks a one-piece.
  • When you move: Sit down, bend over, reach up. A swimsuit that shifts dramatically when you move will be a problem all day at the beach.

Wear What You Love

The old rules about which swimsuit “flatters” which body type were made to make people feel like they needed to hide something — and that’s not what we’re about. We carry cheeky, flirty styles and more covered options because our customers are all different, and all of them deserve something great. The right swimsuit is the one you’re excited to wear. Come in and find yours.
