The underwire should frame the breast and lie flat on the chest. They shouldn’t pinch or come away, you may need to try different back sizes until you find the right one.
The straps should be tight without cutting into the shoulder. If the straps leave pressure marks they should be elongated. Keep in mind: the support of the cups comes from the under band, not from the straps.
When trying on bras, take your time and keep the bra on for a couple of minutes instead of taking it off immediately. Move your arms, sit down and stand up again. It is like walking up and down with new shoes. Like shoes, bras become more comfortable with time. However, if the bra is uncomfortable, tight or pinches, you should try on a different size or a different bra model.Not every bra fits every woman and not every style suits everyone. It mainly depends on the material and the shape of the underwire.In order to find out what suits you best, trying on different bras is unavoidable.Since every woman is built differently there is no formula that applies to everyone. I recommend visiting a specialist shop or a bra expert who can give you tips on what you need to be aware of. You can recognise a good adviser if he or she caters to your individual needs and does not persuade you to buy a specific bra.
