Conversation with Ann-Li Hitosugi

The sizing update was in 2025, and it applied to TRIANGL sizing generally, not just tops. The silhouettes stayed the same, but the fit was updated to feel more true to size, so if you bought before that your usual size may feel a little different now. Size guide:

Sizing-wise, VINCA is now more true to size than older versions. The shape is still the same classic adjustable triangle top with matching bottoms, but if you wore an older VINCA before the 2025 update, the same size may feel slightly different now. If you want, we can help you match your old VINCA size to the current one here:

Go with S top and M bottoms. Since your old set felt too big and the bottoms are what you want noticeably smaller, M is the safer pick for the bottoms rather than dropping two sizes to S. VINCA still has the same adjustable triangle top and side-tie bottoms, so S top and M bottoms should give you the smaller fit you want without going too far. Size guide:

You're right to question that. If your old L bottoms already feel too big and sizing is now more true to size, dropping to S bottoms makes more sense than M. For your VINCA, the better pick from what you've told us is S top and S bottoms. Size guide:

Tie-side bottoms do fit a little differently because they’re adjustable. If your Medium Cheekiest bottoms from last year feel just slightly too loose, Small in the tie-side Cheekiest is the better pick. VINCA uses side-tie bottoms, so it should give you that tighter fit you want. Size guide:

Tie-side bottoms are not inherently bigger or smaller. They’re more adjustable than standard bottoms, so they can feel a little more flexible in fit. If you want a firmer fit, tie-side bottoms can make sizing down easier than a standard bottom style.

If you’re between S and M in tie-side bottoms, yes, we’d suggest S for a firmer fit. The side ties give you a bit more adjustability than a standard bottom. Size guide:
