Fit & Fabric
Made for the beach or pool without looking overloaded
Roomy enough for a real pool day — towel, sunscreen, cover-up, essentials — without turning into a bulky, shapeless bag. At 30 x 19 x 42cm, it fits everything you need.
-
Fabric: water-resistant nylon that wipes clean and holds up against pool water, sunscreen, and sand
-
Wet/dry separation: a separate zip pocket keeps your wet swimsuit or damp towel away from your dry clothes, phone, and everything else in the bag
-
Carry comfort: 3 carry options (shoulder, crossbody, hand-held) — no fiddling with straps all day

At 65, I prioritize comfort and coverage. This suit delivers both without making me feel frumpy. The adjustable straps are a godsend for my sloping shoulders, and the ruched midsection is forgiving. I feel elegant and can comfortably play with my grandchildren. A very pleasant surprise.
usually just wear bikinis but needed something for a family thing so i got the white one. ngl this is actually cute?? the front tie is a vibe and it makes my boobs look good lol. its kinda flattering fr. might even wear it to the beach with my friends 😂
Stats: 5'7", 180lbs, 36D, long torso. Ordered a Large in Green. The material is an 82% nylon/18% spandex blend, feels standard for the price. The adjustable/removable straps are key for my long torso. Tie-back is secure. Removable pads are cheap, took them out immediately. Bottom is medium coverage, not cheeky. Overall a solid 4/5 for fit and function.
OMG YOU GUYS. STOP WHAT YOU'RE DOING AND BUY THIS SUIT. I got the hot pink and I'm LITERALLY OBSESSED!!! 🙌 I have never felt so confident in a one-piece in my entire life. The tie in the front is so cute and you can adjust the straps to be a halter too. I'm 5'2, 125 lbs and the Small is perfect. Just ordered it in black from Tavlux again. ✨
This did not disappoint at all. I’m an XL size with a heavy bust-and fit perfectly hugging my body. I don’t usually wear swimsuits, but this one makes me feel super confident. I love it
Okay, deep breath... I haven't bought a swimsuit in 5 years and I'm terrified after having my son. Here are my stats for anyone else who's nervous: 5'4", 160lbs, 36C. I ordered a Large in black. The ruching on the tummy is actually... really nice? It doesn't suck you in like crazy but it makes me feel less self-conscious. The front tie is cute too. I might actually go to the beach this year.
Love the royal blue color, but let's be real, the 'tummy control' is more like a gentle hug. Don't expect miracles or a magical transformation. It's a nicely ruched panel, that's it. The fit is fine, but the material feels a bit thin. For the price, it's okay, but manage your expectations.
The material feels really soft and comfortable.
This is a great suit for a more conservative beach destination.
The material dried pretty quickly after getting out of the pool.
The material is thick enough that I don't feel exposed.
The ruching isn't as compressive as I'd hoped, but it does smooth things out nicely. Overall, a very flattering suit that I'm happy with.
This is a great suit to wear when you're active at the beach. It stays in place and you don't have to worry about anything slipping.
I have sensitive skin and the material didn't irritate me at all.
The straps can also be worn as a halter, which is a nice option.
I took the pads out, they were a bit small and lumpy. Looks much better without them.
The tie in the front is a bit fiddly to get right, but once you do it looks great.
This is my new favorite swimsuit. Seriously.
I'm currently pregnant and this suit has been great for my growing belly. The ruching provides plenty of room.
