Fit Recommendation

Our bottoms are designed to be cheeky with moderate coverage. They are not thong styles, but they sit low on the hip for a flattering fit. They can also be hiked up on the hip bones for a different fit.

We recommend choosing your true size. If you are between sizes or prefer a more secure fit for swimming and water activities, sizing down will feel more snug in the water.

Size Guide

Size S: Best for sizes 0–4
Size M: Best for sizes 4–6, depending on hip width
Size L: Best for sizes 6–10

Founder Fit Note

Natalie is a 26" waist and typically wears a size M for the best fit due to wider hip bones. Those with narrower hips or who prefer a more snug fit may prefer a size S.

A typical size 4 wearer with a larger bum and 5'6 in height preferred a size M for coverage
