How to Get the Fit Right

Measure snugly under the bust for your band, then around the fullest part of the bust for your cup, keeping the tape level all the way round.

Between two band sizes? Go down a band and up a cup — the volume stays the same and the support improves. The band should sit level across your back and stay put when you raise your arms; if it rides up, the band is too big.

Care Guide

Hand wash cool with a mild detergent and reshape the cups while damp, or machine wash on a delicate cycle inside a lingerie bag.

Air-dry only, away from direct heat — heat is what breaks down elastic, and it's the main reason a bra stops fitting. Store moulded cups stacked, never folded inside out.

View full details

The right suit changes how the whole day feels. No tugging, no checking, no towel until you want one.

Smooth From Bust to Hip

One continuous panel means no waistband to roll and no gap where two pieces meet — the cleanest line in the water.

Shaping Built Into the Lining

A double-layer front panel smooths through the middle without the suit feeling tight anywhere else.

Holds Its Colour

Chlorine- and sun-resistant yarn, so it looks the same at the end of the season as it did at the start.

What You Get

  • Smooth From Bust to Hip
  • Shaping Built Into the Lining
  • 11 colours to choose from
  • Sizes S to 2XL (5 sizes)

Size & Fit

Available S to 2XL. Check the size chart against your own measurements before ordering — if you're between sizes, size up for a relaxed fit or stay true to size for a closer one.

Care

Machine wash cool on a gentle cycle with like colours, and air-dry where you can. Heat is what breaks down elastane, and elastane is what keeps the fit.

Henrietta
Henrietta ★★★★★ 5/5

I was looking for a modest swimsuit to wear for church camps as a youth leader and I came across this beautiful swim dress! I really liked the pattern, shape of the neck line and the cute tie up detailing! The one thing I wish it had was a longer torso with the cup pads a bit higher. It felt like I was fighting to get a bit of coverage up top and lift. The skirt portion also has an interesting sewn seam. Nothing super out there, but I did find it a bit strange and with the color of the suit, the white thread did stand out a bit. Overall, the suit was well made and comfortable. I got lots of compliments from the other young gals at my church!I didnt see women in there 20s without kids posting reviews, so here I am, helping a sister out!I got a size Small, Im about 127-132lbs, athletic build, and a 32D. Hope this helps someone else!

I bought this to go on a tropical vacation. I'm 5'6", 150 lbs., 38DD. The medium was perfect for me. This is the first one piece bathing suit I've been able to buy in decades. If it fits on top it is way too big on bottom. This one is perfect. What a rare find.The wrap-like attached skirt is really flattering. It isn't super modest on top but a good balance of coverage and exposure. It stretches a little when it gets wet but not so much that it's too big and it shrinks right back when it dries. So far it holds its color. The black is very figure flattering.I got tons of compliments! This was a great purchase.

This swimsuit is EXACTLY what I was looking for! I am a mama of 2 now and my body has definitely changed and taken a toll! And being a mama I wanted something modest but still cute! This swimsuit hugs in all the right places and covers all the places youd want to be covered! The quality is AMAZING! Ive always bought my swimsuits at Walmart so definitely way better quality ?? this is not even a joke get this swimsuit! The straps are adjustable and the material is so smooth and soft! I really have no complaints and thats hard for me! GET ITTTTTT!!! Also Im 5 feet and anywhere from 135-140 lbs

This suit fits me well. Some tummy control. Was a bit of a struggle to get into since the stitching across the top didnt stretch much. I heard a few stitches pop and when I took it off I stretched it good. A few more pops and now its nice and stretchy. I dont see anywhere that needs repaired so far. Im 70, 51 136 lbs and I am comfortable with the coverage. I may add a stitch or to to the skirt opening so it doesnt go up so high. Otherwise I am pleased with my purchase.

I swore my entire life I would never wear a swim dress. This changed my mind! The skirt gives a very sarong like feel to the over all style of the swimsuit. My only complaint is I do have a longish torso so I feel like the cut was a little high, however I was still comfortable wearing this because the skirt covered my insecurities. I'm a mom of two who never officially bounced back and this swimsuit gave me the confidence to play on the beach with my kiddos.

Juliana
Juliana ★★★★★ 5/5

Modest, flattering, sexy all in one. Cute style. I ordered in an M but it was too tiight in the bust and just right on the bottom. I exchanged for an L. Its just right in the top while being loose on the bottom, but because it has a skirt, I dont think it will be noticeable.not much tummy control. Im 71 and a half and wanted a nice-looking sit for an older woman. This suit delivers on that.

I needed a bathing suit for an up and coming pool party and this is cutest bathing suit I have! Im 52 and 113lb I got it in a size S and Im actually surprised how good it looks and fits and was a bit surprised how well its made too. Built in cups, and bathing bottoms and adjustable straps! Super cute, you can even in untie it and turn it into a little dress I love !

Happy
Happy ★★★★★ 5/5

Love this suit! Great support in the chest area and throughout the body. Adjustable straps help keep the fit where you like it. Perfect coverage for those of us with a tummy. You can untie or adjust the skirt portion which surprised me but might come in handy! Colors are great, just as pictured! For size reference Im 54 around 190lbs. Very short torso and long legs!

Star
Star ★★★★★ 5/5

I am a 54 and 130lbs mom. Needed something that my kiddos can grab onto if they feel uncomfortable in the pool, makes me feel confident but doesnt show off my hooha at the beach with all of my family. Love the bra padding that does not move around! Wish there were more solid color options! Ill probably get the dark blue or black. Great bathing suit so far!

Love this one piece swim suit! It fits me just right and covers up the areas I wanted. I love that the little skirt adds some extra coverage but still makes the swim suit super cute! Very happy with the fit, color and style! The elastic material also sucks in my tummy for extra support.

Im 59 and have a mom pouch and this suit is everything that I have been wanting. Tummy control, tummy coverage and doesnt let the arm fat by the bra area roll over! Also has adjustable straps for us tall girls! 10/10

Saw an influencer share this dress and loved it. The fabric is great, good coverage, and the colors are so pretty! I would have never picked this out unless I saw it on someone else so had to share!

Frequently Asked Questions

How do I find my size?

Measure snugly under the bust for your band, then around the fullest part for your cup, keeping the tape level all the way round. Match both to the size chart on this page.

Between two bands? Go down a band and up a cup — the volume stays the same and the support improves.

Will it show under fitted clothes?

Seamless and moulded styles are chosen specifically so the edge doesn't print through. Lace styles are finished flat, but under very thin jersey the lace texture can still read — pick a seamless style if that matters to you.

What if the fit isn't right?

Get in touch with your order number within 30 days and we'll arrange an exchange or a refund. Items need to be unworn with tags on.

How should I wash it?

Hand wash cool and reshape the cups while damp, or machine wash on delicate inside a lingerie bag. Air-dry only — heat is what destroys elastic, and it's the main reason a bra stops fitting.

Wireless or underwire — which should I pick?

Underwire gives a more defined lift and holds shape under structured clothes. Wireless spreads support through the band and wins on comfort over long days. Both are graded across the same size range.

How long does delivery take?

Free shipping on every order, delivered in 5–10 business days. You'll get a tracking link by email as soon as your parcel leaves us.
