Description
The swimsuit you keep on from your morning swim to your drink at sunset.
You walk out to the pool and leave the cover-up on the chair. No sucking in. Your waist looks cinched, back rolls disappear and your tummy is held smooth and flat. You end up in the photos instead of behind the camera.
The hidden layer. There's a shaping layer inside. Soft mesh pulls in your waist, tummy and back, and the ruching on the front smooths everything over. It's the suit, not luck.
Fit it to you. Adjust the straps and the U-ring at the front until it sits right.
Pick your lift. The built-in cups come out, so you decide how much lift and support you want.
In the box: one shaping one-piece in 52% nylon and 48% spandex, with a breathable shaping lining, removable cups and adjustable straps.

Held in, lifted up.
The hidden layer
Soft mesh inside pulls in your waist, tummy and back. That's the suit doing the work.
Ruched to smooth
The gathered front keeps your tummy flat all day.
Lift you choose
Removable cups lift and support your bust, and nothing spills out.
Set to you
Adjust the straps and the front U-ring to fit you. It's one layer, so it's easy to get on and off.

Leave the cover-up on the chair
You know the routine. The cover-up never comes off, you hold your stomach in all afternoon, and later you crop yourself out of the picture.
In this suit the cover-up comes off. The shaping keeps your tummy flat and your waist cinched, so you can stop working at it and just enjoy the day.

If you've given up on swimsuits
Mom tummy. Fuller bust. Softer skin since the scale changed. A drawer of suits that promised more than they did.
This one was drafted for bodies after kids and weight changes, not on a size 4.
MiaShape vs. the usual swimsuit
A regular swimsuit meant holding your stomach in all day. Shapewear underneath meant hoping it wouldn't show. Here's the difference.
Which size should I order?
With a soft tape, measure your bust, waist and hips over your underwear, breathing normally. Then find your numbers in the size guide. It goes by real measurements, not a vague "runs small".
I'm a bigger cup. Will it hold and lift me?
It's made to hold you, not let you spill out. The removable cups lift and support, and the shaping panel keeps everything steady. Cups in for more lift, cups out for less. Your call.
It looks great on the model. Will it look like that on me?
Fair question. The suit does the work: a hidden mesh layer pulls in your waist, tummy and back, and the ruched front smooths your belly. That's how it's made, not the model's genes, so it works the same on your body, kids and all.
How do I get it off wet? Can I still use the bathroom?
Yes. It's one piece with a normal pull-down bottom, so bathroom breaks are easy even when it's wet. No peeling off two soaked layers like with shapewear under a swimsuit.
Is it see-through?
No. There's a shaping lining under the 52% nylon, 48% spandex outer fabric, so it's lined, not one thin layer.
Is it comfortable all day, or does it dig in?
You set it. The adjustable straps go where they sit right and stay there, without sliding or cutting in. It holds you firmly where the shaping is, and you adjust the rest.
Can I actually swim in it?
Yes. It's a one-piece swimsuit made for in and out of the water, in high-stretch 52% nylon and 48% spandex, with straps that stay put. Put it on, swim, climb out, dry off.
Are the cups removable?
Yes. They're built in, but you can take them out. Leave them in for more lift and support, or take them out for less.
How should I wash it?
Gently. Take the cups out first, then hand wash in cool water. No dry cleaning, ironing, bleach or tumble dryer. Dry it flat or on a hanger and it keeps its shape.
Wrong fit? Can I exchange or return it?
Yes. Your first size exchange is free. Email support@miashape.com and we'll swap it for the right size. Guessing your size wrong shouldn't cost you.
