I go braless. I have all my life. When I was 12 my mother took me to be fitted for a bra. We came home with three. Much excited I put the first one on. It lasted a very short time and then it came off -- none of them were worn again. That was 41 years ago.
I've owned very few bras in that time. I bought a few -- from bra departments in reputable stores with a 'fitter' and yes, have found the bra to be comfortable 'for about an hour' then it's a battle to take my focus off how uncomfortable I am wearing the darn thing until I can get home.
My answer -- and it precludes perky breasts pointing to the sun -- is to wear close fitting singlets. I'm in Australia and that's what we call that part of our underwear. If you don't call them that in the U.S you could do a search but I'm pretty sure they equate with your 'tank' tops. Although they are underwear. I weawr both the sort that are meant to be underwear and the sort meant to be outwear. I wear them under everything. At 53, I must admit I don't want my nipples on high beam to the world and I don't want them jiggling around too much so a close fitting singlet works in this regard.
I have the three basic colours. Black, white, and skin toned and they work for me. I'm 53 and my breast are naturally going to sag. But they sagged way before this. I breastfed three children and that did the trick for sagging when I was very young.
I think bras are a bit like 'whalebone corsets' only not as bad, obviously. We are being sold the idea that our breasts should be a certain height and not move around just like woman used to be sold the view that their waists should be a dainty little circumfurence and their breasts should protude forth like the bow of a big ship.
I am aware that some big women feel more comfortable in bras and I'm sure they do. But for this woman a singlet makes me feel modest enough and comfortable at the same time. Let's face it. Eveyone knows, short of having very small breasts and being lucky, or surgery, that breasts go south with age. In my case wearing a bra is a bit like real life air brushing. I'm just kidding everyone and feeling very uncomfortable physcially while I'm doing it.
I have one arrangement though to appease my 32 year old daughter. I will wear bras to my children's weddings. Don't ask me why this is so important to her but I don't argue over this small point. So far only one has been married and I'm hoping by the time the next one does, she will have gotten over this rather strange request.
I have a feeling bras, fitted professionally or not, are only comfortable for about an hour after you put them on. That's how they get to sell them. A nice singlet or pretty coloured fitting stretch cotton camisole is such a much nicer alternative in my opinion -- so much more comfortable.
As you can tell, bras and I never did do well together. LOL.
