Costa Rica’s beaches aren’t just backdrops for your holiday photos – they’re places where sun, salt and style meet. From surf towns to sleepy coves, you’ll see everything from sleek one-pieces to barely-there bikinis. The trick is choosing what makes you feel gorgeous, confident and still respectful of local culture.
What’s the general swimwear vibe on Costa Rica’s beaches?
Most beachgoers in Costa Rica dress modestly trendy, with cheeky cuts fairly common but topless sunbathing generally not accepted.
You’ll find:
- Classic two-piece bikinis in bright tropical prints, often with slightly cheeky bottoms that show off sun-kissed curves without going full Brazilian; picture someone walking to a beach bar, sarong tied low on the hips, bikini top peeking out under a loose linen shirt.
- Stylish one-piece suits that are anything but frumpy, from deep V-fronts to low backs and subtle cut-outs; think of a sleek black suit that hugs the waist, perfect for slipping from morning swim to poolside cocktail with just a pair of oversized sunglasses.
- Surf and rash vests paired with bikini bottoms, especially in strong-sun spots like Guanacaste; a cropped rash top over a high-cut bottom looks sporty and playful, and lets you paddle out without worrying about wardrobe mishaps.
- Easy cover-ups – sarongs, oversized shirts, floaty beach dresses – thrown on to stroll into town; imagine a gauzy white dress skimming over damp swimwear as you wander into a café for an iced coffee.
Locals and long-term expats are used to every style under the sun, but the overall mood is relaxed, attractive and never deliberately provocative.
Is a two-piece bikini a good choice for Costa Rica?
A two-piece bikini is ideal for Costa Rica if you want maximum sun, mix-and-match freedom and a bit of playful glamour on the sand.
Why a two-piece works so well here
- It’s brilliant for sunbathing, as more skin can enjoy the warmth; you can undo the back strap while lying face down, then slip it back on to walk to the bar without feeling exposed.
- Mixing and matching tops and bottoms lets you play with colour and mood – a coral triangle top one day, paired with a high-waisted palm-print bottom the next, so you feel like you’ve packed twice as many outfits.
- Fabric dries quickly between sea dips, so you can swim, stretch out on a towel, then wander the shoreline without feeling damp and chilly against your skin.
- In the sticky heat, having your midriff bare feels deliciously cool; a simple bandeau or halter top with low-rise bottoms can make you feel almost weightless in the sea breeze.
What to consider with a two-piece
- Strong Pacific waves can easily tug at loose tops or flimsy tie-sides; that cute string bikini you love for pool days may need an extra knot or a sturdier backup if you’re body-surfing at Playa Hermosa.
- Strapless bandeau tops look fantastic for sunset cocktails, but can slide down when you dive through waves; they’re better for lounging on a sunbed than tumbling in shorebreak.
- Very tiny tops might feel out of place on a packed family beach at midday; the same bikini that works at a chic beach club may feel too revealing on a quiet village stretch where abuelas are walking their dogs.
For days centred on tanning, strolling, taking photos and flirting gently with the camera rather than the waves, a two-piece bikini is sheer joy.
When is a one-piece swimsuit the better option?
A one-piece often wins on active days, offering secure support, flattering lines and a quietly seductive feel that doesn’t need to shout.
Why a one-piece feels amazing in Costa Rica
- It stays put when you’re moving – from surf lessons to paddleboarding; you can lean forward on the board or tumble off laughing without grabbing at your top.
- The extra fabric gives a gentle hug around your middle and bust, which can feel wonderfully reassuring when waves are strong or you’re jumping from a boat into deep blue water.
- It offers more sun protection over your torso, handy when you’ve already earned a bit of colour and don’t fancy burning your stomach on day three.
- Modern designs can be incredibly chic: imagine a deep emerald one-shoulder suit, with a low scooped back and high-cut leg that elongates your silhouette as you walk along the waterline.
If you want to feel sexy and secure, a one-piece can be the ultimate confidence suit – especially on beaches where the surf has more power than you expected.
Are thong bikini bottoms acceptable on Costa Rica beaches?
Thong and cheeky bikini bottoms are widely seen on tourist beaches, but it’s important to balance flirtatious style with awareness of who’s around you.
You’ll see cheekier cuts:
- On popular, international beaches like Tamarindo, Jaco, Santa Teresa, Nosara and Manuel Antonio, where groups of friends and solo travellers sunbathe in small, sculpted bottoms that show off strong legs and hours in the surf.
- Among surfers and younger travellers who pair a sporty top with a high-cut thong bottom, so tan lines stay minimal and there’s no extra fabric clinging to wet skin.
- Around beach clubs and hotel pools, where loungers, cocktails and DJ sets create an atmosphere that suits bolder, fashion-forward cuts.
More covered styles feel better:
- On quiet, traditional village beaches where local families are picnicking and children are playing in the shallows; a fuller bikini bottom or a mid-rise style feels more in tune with the scene.
- When you step off the beach into small shops or sodas; slipping on shorts, a sarong or a light skirt over your bikini bottom instantly shifts your outfit from “sea” to “street”.
Think of it as matching the mood: you can absolutely highlight your best features, but you don’t need to shock anyone to feel sensual.
Is topless sunbathing allowed in Costa Rica?
Topless sunbathing is generally not accepted in Costa Rica, and keeping your bikini top on is the respectful choice in almost all situations.
Even on beaches with a very international crowd, going topless can draw unwanted attention and make locals uncomfortable. If you want fewer tan lines:
- Choose a thin-strapped or bandeau-style top you can discreetly adjust while you’re lying on your towel.
- Use self-tan or a strapless swimsuit top for evenings out, rather than taking your top off on the beach.
- Pack a pretty, semi-sheer cover-up that still feels light and sensual but covers enough when you walk away from your sunbathing spot.
Sexy in Costa Rica is more about confidence, ease and attitude than baring absolutely everything.
How do I choose between a one-piece and two-piece for my Costa Rica trip?
The best choice depends on what you’ll be doing, how much coverage you like, and which style makes you feel most like your favourite version of yourself.
Pick mostly two-pieces if:
- Your days are built around long, lazy sun sessions with occasional dips in the water; you can stretch out on your towel, feel the breeze across your skin and enjoy that “golden hour” glow on your shoulders and midriff.
- You love playing dress-up with colour and pattern, switching from a bold jungle print one day to a soft neutral the next, matching your bikini to your mood and the sunset.
- You’re chasing minimal tan lines so your evening outfits – from strappy dresses to off-the-shoulder tops – look as clean and flattering as possible.
Pack at least one one-piece if:
- You’re taking surf lessons or you know you’ll say yes to every adventure – boogie boards, boat trips, waterfall swims – without wanting to think about your top shifting.
- You like having a “safe” swimwear day for when you’re feeling bloated, sun-tender or just not in the mood to show as much skin; a beautifully cut one-piece can feel like wearing elegant lingerie under your clothes.
- You plan to visit both laid-back surf towns and more traditional coastal communities, where a slightly more covered option feels more comfortable.
Most travellers are happiest with a mini “swimwear capsule” of three pieces:
- One sporty one-piece that can handle waves and wild jumps off boat decks.
- One reliable, comfortable bikini you’d happily wear all day from breakfast to bonfire.
- One show-stopper set that makes you feel irresistible for pool parties, sailings and sunset photos.
What other beachwear should I pack for Costa Rica?
The best Costa Rica beach wardrobe smells faintly of salt and sunscreen and works from hammock to happy hour with a couple of quick tweaks.
Useful extras include:
- A soft sarong or pareo that can be a skirt, dress, makeshift towel or even a shawl on a breezy night; wrap it high for a glam look or low on the hips for a laid-back feel.
- A light cotton or linen shirt you can throw over a bikini, knot at the waist and wear into town with denim shorts, looking effortless rather than overexposed.
- A wide-brimmed hat or classic cap to shade your face; pair it with oversized sunglasses and suddenly your simple swimsuit looks like part of a curated holiday wardrobe.
- A rash vest if you burn easily or plan to surf; worn over a bikini bottom, it can actually look quite alluring, hinting at the shape beneath while protecting your skin.
- Flip-flops for the sand and sturdier sandals for jungle paths and rocky viewpoints, so you can go from tide pools to cocktail bar without sore feet.
- A quick-dry towel and a small dry bag so you can jump on a catamaran or water taxi at a moment’s notice without worrying about damp clothes or sandy electronics.
With those pieces, you can glide from sun lounger to beachfront restaurant with a couple of easy outfit changes rather than a full wardrobe overhaul.
Do Costa Ricans judge tourists by what they wear on the beach?
People in Costa Rica are generally more interested in your manners than your neckline, and they respond best to relaxed confidence and basic respect.
You’ll make a better impression if you:
- Smile, say hola and treat staff, vendors and locals kindly; a friendly attitude is far more attractive than any swimsuit design.
- Keep your music at a level where you and your friends can dance in the sand without drowning out the sound of the waves.
- Take your rubbish away with you, especially plastic and cigarette butts, so the beach stays gorgeous for turtles, seabirds and the next person who rolls out a towel.
- Observe flags and local advice about currents; nothing spoils a sexy beach moment quite like ignoring warnings and needing rescuing from dangerous surf.
Dress like you’re on holiday, behave like you’re visiting a beloved friend’s home – that combination always looks good.

No. While you might see the odd tourist trying it, topless sunbathing is not part of local beach culture and is best avoided if you want to be respectful.

Three is ideal for most people: one sporty one-piece and two bikinis you can rotate, so there’s always something dry and comfortable ready to wear.
