I hate wearing bras - I find them so uncomfortable. It probably doesn't help that I didn't really wear them until I was in my thirties, after having a massive baby with the subsequent growth in breast size. Before that I could get away with not needing one. I now have the sagging that comes with age and the boost of a bra helps to balance me out style-wise. The only benefit of covid and lock-downs for me was that I could completely do away with the bras again, as I wasn't bothered about being a middle-aged women not wearing a bra when I was only visiting parks, etc.
Is there such a thing as a bra that is completely comfortable? It's that thing about having restriction around your rib-cage that I hate, and that includes sports-type bras, bralettes, etc. What I have been doing, so as not to frighten the horses (or anyone who thinks middle-aged women should not show they have breasts), is wearing bras over camisoles, rather than under; something I'd never have thought of a couple of years ago. However now we're in the summer thinner tops will maybe make this obvious.
