How to size cheeky vs thong — a frank guide

3 June 2026 · by Ander Swim

Two cuts that sit very differently. Here's exactly how each is meant to feel, where to measure, and why mixing sizes between top and bottom is normal.

The cheeky brazilian and the thong look related on a model — same family, same rise. On you, they fit differently enough that the same number can be the wrong size in one and the right size in the other. Here's how to read them.

What 'cheeky brazilian' is meant to do

Mid-coverage at the back — somewhere between full and thong. The leg line should sit high enough to lengthen but not pinch. The seat should lift, never disappear. If you have to tug it down after standing, you've gone a size small. If the fabric pools across the back, go down.

What the thong is meant to do

Bare back, thin band at the top of the hip. The band sits where you'd wear a low-rise jean. Tightness here is the wrong kind — it should hold without printing red after an hour. The leg line is irrelevant on a thong because there isn't one; focus on the waistband instead.

Where to measure

Hips at the widest point, level with the tape — not tilted down to the front. Take the measurement over bare skin or thin underwear, not jeans. Then check the table on our size guide — the centimetre band tells you which size sits without working for it.

Why you might size up in thong, down in cheeky

The cheeky stretches across more fabric, so it forgives a size more readily — the elastane evens it out. The thong has nowhere to redistribute, so if you're between sizes go with the larger. The waistband digging is what kills the wear time on a thong, not the fit at the back.

Mixing top and bottom sizes

Half our customers mix. Buying a top one size up or down from your bottom is the rule, not the exception — bust and hip don't follow one number. The set price applies whichever two sizes you pick.

The vibe check

You should be able to forget what you're wearing within a minute of putting it on. If you're still adjusting after five, it's the wrong size, not the wrong cut.
