Swimwear Fit & Coverage Guide

Every swimsuit we manufacture in Clearwater, Florida is One Size. That is not a limitation — it is by design. Many of our suits feature fully adjustable string ties, which means the fit is customized to your body every time you put one on. There is no S, M, or L to second-guess — the fabric and cut do the work.

The only decision you need to make is how much coverage you want. This guide explains what each style covers, how the strings work, and how to choose the right suit for your comfort level and occasion.

How One Size Works

Many of our bikinis and swimsuits feature adjustable string ties at the hips, neck, and back. Where ties are present, you control the tightness, the height, and the placement. The fabric panels are cut to provide the intended coverage — minimal, micro, or barely-there — and the strings let you dial in the exact fit for your body.

Our four-way stretch fabrics also adapt to your shape. Whether you are petite or curvy, the fabric moves with you rather than against you. The suits are designed to stay in place in the water and look intentional, not accidental.

Tips for Getting the Perfect Fit

For tie-side styles: adjust before you get in the water

If your suit has adjustable ties, set them while standing in front of a mirror. The suit should feel snug but not tight. Once you are in the water, the fabric will relax slightly — this is normal and intentional. For styles without tie-sides, the four-way stretch fabric is cut to fit and will conform to your shape.

Hip ties control coverage and height (tie-side styles)

Tying higher on the hip elongates the leg and reduces bottom coverage. Tying lower gives a more relaxed, fuller-coverage look. Both are correct — it is a matter of preference.

Neck ties control top support

For tops with neck ties, tighter means more lift and support. If you prefer a softer, more relaxed look, tie loosely and let the fabric drape naturally.

Barely There one-pieces: torso length matters

Our barely-there one-pieces have a criss-cross strap design. If you have a longer torso, adjust the shoulder straps to be slightly looser to prevent pulling. The high-cut leg is designed to sit above the hip bone regardless of height.

Fabric Care

We use premium four-way stretch fabrics, velvet foils, holograms, and delicate mesh. These materials require specific care to maintain their stretch and finish:

Hand wash in cold water immediately after every use — chlorine and salt water degrade elastic fibers if left to dry in the suit.
Never machine wash or tumble dry. Heat and agitation will destroy the elasticity and ruin foil and hologram finishes permanently.
Lay flat to dry in the shade. Direct sunlight fades neon and bright colors over time.
Avoid rough surfaces like concrete pool edges and rough sand, which can snag delicate mesh and velvet fabrics.

Deep Plunge One-Piece Swimsuit

Lucy cut this one-piece around the plunge. The V drops low through the center of the front, the legs are cut high on the hip, and the back gathers into a thong so the rear stays light and cheeky.

From the front it reads as one long line from the neckline down to the leg opening. From behind, it wears like a thong bikini bottom.

Fit and coverage

Deep V-front, cut low through the center
High-cut legs
Gathered thong back
One size, recommended for XS–S
Solids, Mist finishes and prints
Some shades are made to order and ship in about 3 days

Strap placement controls the plunge. Let the shoulders sit where they do in the photos; pulling the straps tighter changes how deep the V reads and how the front lies. The photos are your best guide for chest and back coverage.

Who it’s for

Wear it on resort trips, boat days and pool parties when you want one piece that does all the talking. Content creators pick it because the plunge reads from the front, the leg line reads from the side, and the thong back reads walking away, so one suit gives you three different shots.

Ordering questions

How do I choose a color or print?
The selector is grouped to make it quick. The solid shade comes first, then the Mist and pearl finishes, then the prints: animal prints together, followed by the swirls, splatters, painted and multi-color looks. A shade labeled Made to Order, Ships in 3 Days is sewn after you order and usually leaves Clearwater in about three days. Everything else follows the in-stock timing below.

How deep is the front?
It is a true deep plunge. Check the photos for how low it sits, and keep the straps where they are shown so the V stays where it should.

What does the back look like?
A gathered thong back with high-cut legs.

Who does one size fit best?
XS–S.

Where is it made?
Manufactured in Clearwater, Florida.

Is there free shipping, and how fast does it ship?
Free US shipping on orders over $99. In-stock by 2:00 p.m. ET same-day from Clearwater; other in-stock 1–3 business days. Details: shipping policy.

Can I return it?

Care

Hand wash cold and drip dry. Mist and print finishes last longer when you skip bleach, hot tubs, and rough decks.
