I wear a bra because it's more comfortable and it makes me look better. I even wear them on 'pyjama days' sometimes because it's just more comfortable (I have a D cup, and am still growing I think).
It's always funny, when I put on the bra in the morning it's "aah, support", and then in the evening, when going to bed I take it off and it's "aah, freedom". It's just a part of having breasts I think, I like the support they give, but in the end of the day the freedom when taking it off is great too. I only wear bras with underwire that aren't preformed nowadays, as those are the ones that give the best support.
I never wore bras until I started presenting though.
@everyone that has laundry machine damage to their bras, isn't that what laundry bags are for? I always put delicates in a laundry bag.
