How to measure yourself

Bust — measure around the fullest part, wearing an unpadded bra.
Waist — measure around the narrowest part, just above the navel.
Hips — measure around the widest part, standing with your feet together.

Torn between two sizes?

Our seamless knit shapes through its structure, not through tightness. Between two sizes, always take the larger one — a size too small leaves marks and rolls at the waist. For a stronger sculpting effect, choose a firm-control style instead.

Our model wears size S — 5'7", 33"/24"/35"

Description

This tummy control one-piece swimsuit smooths your belly, defines your waist and flatters your curves — without feeling like you're wearing shapewear at the beach.

A fully lined, seamless suit with a built-in shaping panel in front that visibly flattens your tummy while staying comfortable. The full-coverage cut lifts the neckline and smooths your hips in one clean line.

Regular swimsuits dig in or cling to every curve. This one combines the hold of an athletic suit with the look of a dressy one, in a fabric certified to resist chlorine and salt water season after season.

Wear it at the pool, at the beach or on a cruise — and enjoy summer feeling at ease from morning to sunset.

How it slims

A slimming swimsuit doesn't just cover — it reshapes. This one has a double-layer compression panel in front that flattens your tummy, plus side seams placed to nip in your waist and shape your hips. The fabric is denser than a standard swimsuit, so it stays opaque when wet and keeps its shaping power swim after swim.

Tummy control swimsuit vs. regular one-piece

	Elya tummy control swimsuit	Regular one-piece
Flat-tummy effect	Double-layer front panel	None — just a basic lining
Fabric	Dense, opaque when wet	Thin, can be see-through
Waist	Hourglass side seams	Straight cut
Durability	Chlorine- and salt-resistant for several seasons	Stretches out faster
Comfort	Shapes without squeezing	Varies

You notice the difference most when you step out of the water: a thin suit clings to everything, while this one keeps a smooth line even wet.

Who it flatters

A rounder tummy or post-baby belly — the front panel smooths and supports your whole midsection.
Apple shape — the hourglass effect brings the focus back to your waist.
Straight figure — the side seams create a curve at the waist.
After a C-section or if you're self-conscious about your stomach — full coverage that shapes without painful compression.

Plus-size tummy control swimsuit, XXS to 2XL

Every size is graded individually, so the front panel and side seams sit in the right place whether you're petite or plus size. Full lining and dense fabric give opaque coverage at the bust and hips — real plus-size tummy control without squeezing.

Comfortable all day

Unlike stiff slimming swimsuits, this one uses a stretchy seamless knit. A high back and adjustable straps let you fine-tune the fit, and it stays in place without constant readjusting — through a full pool day, a cruise or a beach wedding. Quick-dry with UV protection.

Size guide

Smooth and confident, all day long.

A lot of women skip the one-piece because they think it looks dated. But it's the swimsuit that holds your shape best — as long as it shapes without squeezing.

This one uses a seamless, second-skin fabric with a hidden tummy panel: it nips in your waist and smooths your belly with no visible compression and no underwire digging in. The high-cut leg lengthens your legs, and the low back adds elegance. The fabric stands up to salt and chlorine, swim after swim.

A swimsuit that keeps you looking smooth from your first dive to sunset drinks — without thinking about it.

Designed in France · Made in Portugal · Built to last.
