What to Wear in Costa Rica: 12 Outfits for Every Day of Your Trip
Packing for Costa Rica sounds straightforward until you actually sit down to do it.
The problem isn’t that it’s a complicated destination — it’s that it’s several destinations at once. You might do a rainforest hike, a beach day, a boat tour, and a casual dinner all within the same 48 hours. What works for one will actively fail you in another. Show up with only cute dresses and one pair of sandals and you’ll figure that out fast.
Then there’s the humidity. Lightweight fabrics that are breathable and moisture-wicking are the foundation of any sensible Costa Rica packing list — think linen, quick-dry shorts, and a rain jacket for the inevitable afternoon downpours. Anything that traps heat or takes forever to dry will make you miserable by noon.
Here are 12 outfits broken down by activity — exactly what to wear and how to style each one.
What to Wear in Costa Rica: 12 Outfits Broken Down by Situation
For the Beach & Pool
1. Crochet Bikini + White Wide-Leg Linen Pants
Wide-leg linen at the beach is a better call than it sounds. A sarong keeps retying itself. A skirt gets in the way. Linen pants just sit there and do their job — the wide leg moves enough that you’re not overheating, and white keeps everything clean and airy against the crochet print. You can walk straight from the sand into a beachside lunch without looking like you forgot to get dressed.
How to style it: Tortoiseshell sunglasses pick up the warm tones in a crochet swimsuit in a way plain black frames don’t — that’s the one styling decision worth making here. Straw tote, nothing else. Once you start adding jewelry or accessories you’re working against the simplicity that makes this combination work.
2. Olive Green Bikini + Denim Wide-Leg Midi Pants
The post-beach outfit that means you don’t have to go back to the hotel first. Denim wide-leg midi pants are loose enough that sand isn’t a disaster, long enough that you look like you made a deliberate outfit choice, and the olive green swimsuit top keeps the whole palette earthy and cohesive. Nothing is competing for attention.
How to style it: A single shell necklace at the collarbone is the only addition this combination needs. More jewelry breaks up the earthy color story. Taupe sandals, crochet tote, done.
3. Floral Bikini + White Linen Coverup + Raffia Wedge Sandals
For beach days that turn into lunch, which will happen more than once. The coverup means you’re actually dressed when you drift into a restaurant, and the wide-brim hat is the detail that elevates the whole thing from beach outfit to something that looks intentional. Without the hat it’s fine. With it, the entire look reads considered.
How to style it: The wedge sandal rather than a flat is what tips this from casual-beach into something worth photographing. If your hair is up, tuck it under the hat. If it’s down, leave it loose. Either way this works.
4. Black Zip Rash Guard + Denim Shorts
The boat tour and water activities outfit. Bring two swimsuits so one can dry while you wear the other — and for water activities, a rash guard is worth the space it takes up in your bag. The zip-front design is what makes this feel like an actual outfit rather than protective gear. Black on denim is clean and simple and requires no decisions — which is exactly what you want on a day that already has a lot going on.
How to style it: Rectangular sunglasses and a striped tote. Nothing else. Tie your hair back before you board — not after the wind has already done its damage.
For Hiking & Adventures
5. Sports Bra + Athletic Shorts + Trail Sneakers
The casual nature walk or easy trail doesn’t need an overthought outfit. A crossback sports bra keeps you cool without looking sloppy, and structured black shorts give the whole thing enough intention that it doesn’t look like you grabbed whatever was on the floor. The simplicity is the point.
How to style it: A backpack is non-negotiable — water, sunscreen, and bug spray all need somewhere to go. Keep sunglasses on throughout. Even on what feels like a gentle trail, the sun finds ways to surprise you in Costa Rica.
6. Bikini Base Layer + Quick-Dry Shorts + Hiking Boots
Waterfall hike days have one rule that overrides everything else: get the footwear right. Flip flops, regular sneakers, and standard sandals all fail on wet rocks and river crossings. Sturdy lace-up hiking boots or water-resistant trail shoes are the entire point of this outfit — everything else (ruched cami, athletic shorts, quick-dry fabric) is comfortable and fine, but wrong footwear makes none of it matter.
How to style it: A bucket hat with a chin strap worn properly — not just sitting on your head. When you’re moving through water and wind, the strap is there for a reason. Black backpack, boots laced correctly, done.
7. Bikini Top + Denim Shorts + White Windbreaker
A rain jacket is essential for full rainforest days — quick-dry fabrics and light layers that you can add or remove as the temperature shifts throughout the day are the approach that actually works. Here’s how those days go: you start cool, heat up by midmorning, it rains by early afternoon, you’re glad you have a jacket, then it clears. The lightweight windbreaker tied around the waist when it warms up means you’re never carrying too much, and the bikini top underneath gives you flexibility as the temperature moves around.
How to style it: A hip bag over a backpack — keeps your hands fully free and your essentials accessible without stopping to take anything off. White sneakers will get dirty on a day like this. Accept it in advance.
For Towns & Markets
8. Floral Halter Top + Olive Wide-Leg Pants
The market and town-wandering outfit. Olive wide-leg trousers are comfortable for a full day of walking and the color is doing genuine work — not boring, not loud, just grounded. A floral halter top keeps the tropical energy without trying too hard, and everything pulls from the same green family without competing.
How to style it: A shell charm necklace at the collarbone and stop completely. More jewelry breaks the palette and you’ll be tempted to add it — resist. Birkenstock sandals, straw tote.
9. Oversized Graphic Tee + Red Crochet Mini Skirt
The tee has to be genuinely oversized — not slightly cropped, not fitted, but really big, as if you picked it up without thinking. That’s what makes this combination work. The red crochet mini is loud in the best possible way and is doing all the talking, so the tee needs to be the opposite. Tucked loosely at the front and left relaxed at the back, no further effort required.
How to style it: A bold skirt and a statement tee is already a full look — resist the instinct to add more. Tortoiseshell sunglasses, crochet tote, wedge sandals for a little height. Leave it there.
10. Crochet Bikini Top + Denim Mini Skirt + Bandana
A bikini top worn as an actual top works completely in Costa Rica — nobody looks twice. The denim mini skirt keeps it from reading purely as beach and the platform sandals push it further into outfit territory. The underrated detail here is the bandana — navy or neutral, tied loosely around the neck or knotted in the hair — which does double duty against the humidity that will show up mid-morning regardless of what you planned.
How to style it: The bandana is the entire detail. Tied at the neck, looped on the bag handle, knotted in the hair — it’s versatile and it’s the thing that makes the look feel considered rather than thrown together. Straw tote, done.
For Evenings
11. Floral Halter Midi Dress + Kitten Heel Sandals
There’s a specific kind of dress that makes immediate sense the second you land somewhere warm. A floral halter midi is that dress. You put it on and don’t think about it again for the rest of the evening — it handles itself. The kitten heel is the right choice over flats here: resort paths after dark are often uneven and dimly lit, and a full heel creates unnecessary risk, but a small lift means it doesn’t read as daytime.
How to style it: Gold drop earrings and skip the necklace. Woven mini bag, hair loosely down. That’s the complete look — adding to it makes it less, not more.
12. Brown Halter Maxi Dress + Gold Strappy Heels
For evenings when you actually want to look dressed up rather than just dressed. A chocolate brown halter maxi with a side slit photographs exceptionally well in warm evening light — the color does something that white or floral simply doesn’t, giving the whole look a more intentional, considered quality. Gold strappy heels underneath keep it elevated without being overdressed for a beachside dinner setting.
How to style it: Lean fully into gold here — hoops, a ring stack, the works. Gold against chocolate brown works in a way silver never would. A beige ruched mini bag provides the contrast that keeps the gold from becoming too much. The instinct will be to keep adding — don’t.
Final Packing Thoughts
The honest reality of what to wear in Costa Rica is that less goes further than more. According to MytanFeet’s Costa Rica packing guide, the country has several distinct climate zones — beach coasts are hot and humid, mountain areas like Monteverde can drop to the 50s°F at night, and the Caribbean coast can rain at any time of year — so tailoring what you pack to your specific destinations makes a real difference.
The place moves at its own pace and the simplest outfits tend to work hardest there. You’ll be too occupied with what you’re doing to overthink what you’re wearing — and that’s exactly the point of going.
