Most of the support comes from the underband. It should be horizontal around your body without riding up or digging in. We recommend fastening a new bra on its loosest hooks so that you can tighten it if it stretches over time.

The underwires in your bra should sit flat on your ribcage (not your boob!) all the way round to your armpits. The wires between your boobs should lie flat against your chest without digging in, rubbing or poking out.

Make sure your boobs are fully in the cups – a bit of a scoop, wiggle and jiggle usually does the trick! You should fill the cups without any bulging or wrinkling even in a lower-cut style and there should be a smooth line, with no ridge, where the top and the side of the fabric ends.
