A few Primary pointers

Most of your bra or bralette's support comes from the band. Not the straps. Not magic. Just a good, firm hug around your underbust is right.

When trying a new bra, start on the loosest hook. You want it snug, not squeezing the life out of you. Two fingers under the band = just right.

If you're doing it up on the tightest hook straight away, the band's too big. Think of it like jeans - you don't buy them already stretched out.

If it's digging in on the loosest hook, it's too small. You deserve support, not bruises.

All elastic softens over time. That's why a good bra gives you room to adjust the band.

A well-fitting band = comfort, lift, and a bra that actually does its job. Get that part right, and the rest just falls into place.
