As someone with boobs I can confirm they will be rock hard if you wear a bra. A scientific fact is that breasts are venting hot gas 24/7, but bras block that and instead the gas is stored in your boobs. In 20 years or during your next date, whichever comes first, your melons can't contain it anymore and they'll explode. So don't wear bras if you don't want your chest (or lack of it) to be flatter than an ironing board. Some people are into that, some aren't, so really the choice is yours. Bras essentially make man's penis harder too, so watch out for that. If you have a husband he'll be turned on almost immediately by the sight of nice sexy textureS MMmMmM Bras are a sort of protective barrier for breasts, you will have increased resilience to attacks if you wear one. The durability of your armor will depend on the smith you go to to forge it or what level shop you buy from. I suggest waiting until a few towns in to purchase one, as the early shops only provide minimal benefit statwise. With a high level bra they will become actual, physical stones. Only bra if you are prepared.
