Swimwear Size & Fit Guide: How to Choose Your Size

SAMESAME SWIM sizing and fit guide for bikini tops and bottoms

Getting Your Size Right the First Time

Nothing kills the excitement of a new bikini faster than it not fitting the way you pictured. Since our tie-side and tie-top styles work a little differently to fixed-band swimwear, here's how to get it right before you order.

Tops: Tie vs Fixed vs Bandeau

Our tie tops, like the Tangerine Dream Tie Top and Guava Dream Tie Top, are the most forgiving option since the ties let you adjust for a snugger or looser fit around the band and neck. If you prefer a cleaner line with no ties at the back, a fixed style like the Tangerine Royale Hip Top gives a more structured, no-adjustment fit — so sizing accurately matters more here. Bandeau styles, like the Lemonade Dream Bandeau Top, sit without straps, so we'd always recommend true-to-size or sizing up if you're between sizes for extra security.

Bottoms: Cheeky Cuts Run True, But Check the Hip

Most of our bottoms, including the Guava Dream Tie Bottom and Lemonade Dream V Bottom, are a cheeky cut designed to sit low on the hip. If you're between sizes, we generally recommend sizing up on bottoms for more coverage and a comfier fit through the day, especially if you'll be moving around a lot (think beach volleyball over sunbathing).

Measuring Before You Buy

Grab a soft measuring tape and measure around the fullest part of your bust for tops, and around your natural waist and hips for bottoms. Compare those numbers to the size chart on each product page rather than guessing from your usual clothing size — swimwear sizing runs differently to everyday tops and bottoms.

Still Not Sure?

If you're local, you're welcome to try pieces on in person at our Miami, QLD store — seeing the fit and fabric in person is the easiest way to remove any guesswork. Otherwise, our size guide on each product page is the best starting point, and our team is always happy to help if you're stuck between two sizes.
