To help guide you through the process, here are the key points you should look for when checking the fit of your bra.
1. THE BRA UNDERBAND
This part of the bra provides the majority of the support so it is important that it fits firmly, parallel to the cups. Look in the mirror and check that the band is at the same level all around your body.
When buying a new bra, fasten it on the first/outermost row of hooks. This will allow the bra to be tightened as the under bust band starts to get slightly looser after you’ve worn it a few times.
If the band rides up at the back it is probably too big. Please choose a smaller under band size and go up a cup size.
2. THE STRAPS
They should sit parallel or slightly V-shaped on the back.
If the straps are digging into your shoulder it might be a sign that the under bust band is too big and not giving enough support. Try a smaller under band size and a cup size bigger.
If the straps, after being adjusted, are slipping down your shoulders it might mean that the under bra band is too small. Try a bigger under band size, and consider trying a cup size smaller.
3. THE CUPS
The cups of a bra, especially when underwired should go right around the contour of the breast sitting flat against your ribs without digging in. You should also fit neatly into the cup with no excess of flesh showing on the sides of the cup or spilling out over top. This applies even when wearing push-up or low cut bras. Before you change the cup size, please make sure that your boobs are completely “dropped” into the cups. Lean a bit forward, lift and jiggle them into the cup and smooth out the sides.
If you feel the underwire is digging in, try going one cup size bigger, but keep the under bust size the same.
If the under band is curling up or standing away from the body, the cup is probably too small, go up a cup size, keep the under bust size the same.
If the cup puckers and looks baggy it is probably too big, so try a smaller cup size with the same under band size.
4. THE CENTRE FRONT OF THE BRA
The centre front of the bra sits between the breasts and is also called a bra bridge. The bra bridge should lie flat against the body. If there is a gap between the bra bridge and your rib cage, or the bra bridge sits on top of your breasts, it might mean that the cup size is too small. Try to go up a cup size, keeping the under bust size the same.
