FAQs

It’s a minimal, lower-coverage top with added security compared to a classic triangle bikini.

Is this top supportive or more minimal?

It’s best for lower-impact movement, swimming, beach days, and active travel when you want a lighter fit.

What activities is it best for?

It fits true to size. Use your underbust measurement first, and size up if you’re on the bustier end or want more coverage.

How should I choose my size?

The Triangle Top has a smaller, more minimal fit. The Sport Top offers more coverage, compression, and support.

How is it different from the Sport Top?

Pair it with the Thong Bottom for the most minimal set, the Sport Bottom for balanced coverage, or the 3" Swim Short for a more covered look.

Got questions?
we got answers

Find quick answers here, or explore the full FAQ for more details.

How do I choose between the Sport Top and Triangle Top?

Choose the Sport Top if you want more coverage and support for swimming, workouts, and higher-movement days. Choose the Triangle Top if you prefer a smaller, more minimal fit for lower-impact activities.

Can I mix different top and bottom sizes?

Yes. Surface pieces are sold separately, so you can choose the top and bottom size that fits your body best instead of forcing yourself into one set size.

Which bottom should I pair with the Sport Top?

Pair it with the Sport Bottom for an all-around active fit, the 3" Swim Short for more coverage, or the Thong Bottom for minimal coverage with a secure feel.

What if I’m between sizes?

For tops, start with your underbust measurement first. If you prefer a more compressive performance fit, stay true to size. If you want more room or coverage, consider sizing up.

Is the fabric see-through when wet?

The pieces are designed with targeted lining where coverage matters, while keeping the rest lightweight and fast-drying for comfort in and out of the water.

How should it feel when I first try it on?

It should feel secure, not loose. A slightly snug fit is intentional because the fabric is made to adapt to your body while still holding its shape through movement.
