Wondering what to wear over swimwear once you step off the sand? It's one of the most-asked questions our styling team gets at BERLOOK, and the honest answer is that the right layer does three jobs at once: it turns your swimsuit into an actual outfit, it shields your skin from the sun, and — something almost no cover-up guide mentions — it helps your skin stay healthy after a swim.
Below you'll find our seven favorite pieces to wear over a swimsuit, styling ideas for every scenario, and the fact-checked reasons dermatologists and OB-GYNs care about this topic more than you'd expect.
Key Takeaway
The best things to wear over swimwear are lightweight, breathable layers that slip on easily over a damp suit and still look intentional away from the water:
- A sarong or pareo (the most versatile option)
- A breezy beach dress
- An oversized button-down shirt
- A kaftan or kimono
- Linen pants or a matching linen set
- A crochet or mesh dress (with one caveat we'll explain)
- Denim shorts with your swimsuit worn as a top
Which one is "best" depends on where you're headed, how sunny it is, and whether your suit is still wet. Let's break it down.
The 7 best things to wear over swimwear
1. A sarong or pareo — the one we'd never leave out of a beach bag
Our honest take: if you only buy one cover-up this summer, make it a sarong. Tied at the waist it's a skirt; knotted at the chest it's a strapless dress; wrapped behind the neck it becomes a halter. It packs down to nothing, dries quickly, and — because it hangs loose — it's exactly the kind of airy layer doctors recommend over a damp suit. The silky rayon sarongs and wrap midi skirts in our Cover-Ups edit are cut generously so the knot sits flat instead of bulging at the hip.
2. A beach dress you can wear straight to lunch
A throw-on dress is the fastest route from towel to table. Look for a relaxed A-line or wrap shape in a breathable fabric that won't cling to a damp one-piece, and go midi if your day might end at a nicer restaurant — longer lengths simply read more dressed. Our beach dresses are designed around exactly this in-between moment: enough coverage for a café, easy enough to pull off for one last swim.
3. The oversized button-down shirt
The most outfit-per-ounce of any option. Wear it open over a bikini, buttoned halfway with the collar popped against the sun, knotted at the waist over high-cut bottoms, or fully buttoned as a mini shirt dress. A crisp white cotton or linen shirt is the classic, though remember the UPF math above — a light shirt is a style layer and a light sun layer, not full protection, so keep sunscreen on underneath.
4. A kaftan or kimono
Kaftans are the resort classic for a reason: one fluid piece, sleeves that cover the shoulders (the spot most people burn first), and enough drama to feel like an outfit. One honest note: many kaftans and kimonos are cut from sheer chiffon, and sheer fabric lets a meaningful amount of UV through. Treat a gauzy kaftan as shade-adjacent, not sunblock — or choose one in a denser weave for long afternoons outside.
5. Linen pants or a matching linen set
Wide-leg linen pants over a one-piece is the most elevated swimsuit outfit there is — the suit reads as a bodysuit and the whole look works for dinner. Linen is one of the most breathable natural fibers and dries faster than cotton, which makes it forgiving over swimwear that hasn't fully dried. It's also the reason we built a dedicated biodegradable linen collection at BERLOOK: the fiber suits beach life and low-impact wardrobes equally well.
6. A crochet or mesh dress — gorgeous, with one caveat
Crochet photographs beautifully and lets your swimsuit show through, which is the whole point. The caveat: by The Skin Cancer Foundation's fabric-construction logic, an open weave offers minimal UV protection — every hole is a window for sunlight. Our verdict: wear crochet for golden hour, boardwalk strolls, and beach bars, and rely on sunscreen (or a denser layer) during peak midday sun.
7. Denim shorts with your swimsuit as the top
The everyday-errands hero. A sleek one-piece doubles perfectly as a bodysuit under denim shorts, and a structured bikini top can pass for a crop top with high-waisted bottoms. Bonus fact most people don't know: dark, densely woven denim is one of the most sun-protective fabrics in existence — The Skin Cancer Foundation notes a dark long-sleeved denim shirt can rate around UPF 1,700. One practical tip: denim traps moisture, so pull shorts over a dry or quick-dry suit rather than a soaked one.
Match the layer to the swimsuit underneath
The cut of your swimsuit changes what works on top. With a bikini, higher-coverage layers — shirt dresses, kaftans, the shorts-and-shirt combo — give you the most range off the beach. A one-piece is the easiest to restyle because it already behaves like a bodysuit: add pants, a wrap skirt, or nothing but sandals and earrings. And if you wear tummy-control or high-waisted styles, wrap skirts and sarongs are your friend — they tie right at the natural waist where those suits are designed to sit, so nothing bunches.
What to wear over a swimsuit: every scenario, solved
| Scenario | Best layer | Why it works |
|---|---|---|
| Beach to casual lunch | Sarong tied as a skirt, or a shirt dress | Airy over a damp suit, polished enough for a café |
| Resort dinner | Midi beach dress or a linen set over a dry one-piece | Full coverage and an elevated look, no outfit change needed |
| Boat day | Oversized shirt plus quick-dry shorts | Handles wind, sun, and splashes; dries fast |
| Errands after the pool | Denim shorts with a one-piece as a bodysuit | Reads as a real outfit, and dark denim blocks serious UV |
| Hours in direct sun | Long-sleeved kaftan or shirt in a dense weave, or UPF-rated clothing | Coverage plus fabric that actually stops UV — sheer layers alone don't |
Cover-up fabrics, compared
A quick cheat sheet based on how fabrics behave over swimwear:
| Fabric | Feel & drying | Sun-safety note | Best for |
|---|---|---|---|
| Cotton | Soft and breathable, but slow to dry once damp | A plain white tee is only about UPF 7, and roughly 3 when wet | Dry days, short strolls |
| Linen | Airy, cooling, dries faster than cotton | Denser linen weaves protect more than gauzy ones | Hot climates, resort lunches |
| Rayon / viscose | Fluid drape, packs down tiny | Moderate; darker colors absorb more UV than pastels | Sarongs and wrap skirts |
| Chiffon, mesh, crochet | Featherlight and decorative | Open structures let UV pass through — keep sunscreen on | Golden hour, beach bars |
| Quick-dry swim fabric (recycled nylon/polyester) | Sleek, moisture-wicking, dries fastest of all | Often denser than it looks; check for a UPF rating | Active days, in-and-out-of-water days |
What you wear over a swimsuit really matters
Before the outfit ideas, two facts worth knowing — because they change which layer you should reach for.
1. Most casual cover-ups block far less sun than people assume
Fabric sun protection is measured in UPF (Ultraviolet Protection Factor). According to The Skin Cancer Foundation, a UPF 50 fabric blocks about 98% of UV rays — but an ordinary white T-shirt offers only around UPF 7, and once it gets wet, that drops to roughly UPF 3. Wet or stretched fabric becomes more transparent to UV light, and loose, open weaves let rays pass straight through. Denser weaves and darker or brighter colors protect noticeably better than pale, gauzy ones. Keep this in mind when we get to crochet.
2. Doctors recommend a breathable layer after swimming — not just for style
Sitting in a wet swimsuit creates a warm, damp environment where yeast and bacteria thrive, which is why OB-GYNs consistently advise changing out of a wet suit as soon as you reasonably can. Mayo Clinic estimates cited by Texas A&M's College of Medicine suggest up to 75% of women experience a yeast infection at some point, and lingering moisture is a known contributor. If you plan to stay in your swimsuit for the day, Piedmont Healthcare's OB-GYN guidance is to choose loose, flowy pieces — think a sarong, a dress, or relaxed shorts — so air can circulate and skin dries faster, and to favor moisture-wicking swim fabric underneath. It's part of why we design BERLOOK swimwear in quick-drying, GRS-certified recycled fabrics: the faster your suit dries, the more comfortably any layer works over it.
Berlook's Exclusive Thoughts
The white cotton T-shirt is the most overrated cover-up going. It clings when wet, turns see-through, and per The Skin Cancer Foundation's figures it offers about UPF 7 dry and closer to UPF 3 soaked — the sun protection of almost nothing. There are prettier and more protective options at the same effort level.
A sarong outworks most single-purpose cover-ups. One piece of fabric converts into a skirt, dress, halter top, scarf, or picnic blanket, and its loose drape is exactly the airflow clinicians recommend over swimwear. That's more real-world utility than a dress that only works poolside.
For sun protection, dark and dense beats light and lacy. It feels counterintuitive in summer, but darker, tightly woven fabrics absorb and block far more UV than pale sheer ones — the same physics that puts dark denim near UPF 1,700. Save the lacy layers for lower-sun hours.
Q&A about wearings over swimsuit
What do you call the clothes you wear over a swimsuit?
They're collectively called cover-ups (or beachwear). The main types are sarongs and pareos, kaftans, kimonos, beach dresses, and shirt-style cover-ups — all designed to slip on over a swimsuit without a full change.
Can you wear a swimsuit as a top?
Absolutely. A one-piece works as a bodysuit under shorts, a skirt, or linen pants, and a supportive bikini top can double as a crop top. If your suit might still be damp, choose one in quick-drying fabric so the outfit stays comfortable — and change into dry pieces when you can.
Should your cover-up match your swimsuit?
There's no rule, but our styling opinion: staying in the same color family always looks intentional. If your swimsuit is printed, pick a solid layer in one of its tones; if the suit is solid, you can go bold with the layer.
Do swimsuit cover-ups protect you from the sun?
Only as much as their fabric allows. Dense weaves and darker colors block meaningfully more UV, while sheer chiffon, mesh, and crochet let much of it through — and any fabric protects less when wet or stretched. For long sun exposure, choose UPF-rated or tightly woven layers and keep sunscreen on underneath.
Warp up
What to wear over swimwear comes down to one idea: choose a layer that breathes, dries fast, and earns its place beyond the beach towel. A sarong, a beach dress, and an oversized shirt will cover 90% of summer situations — and now you know the sun-safety and skin-health reasons behind each choice, not just the styling ones. When you're ready to build your rotation, our cover-ups and beach dresses are made to pair with every BERLOOK swimsuit, in the same planet-friendly spirit as the recycled fabrics they layer over.
