OK, well, anyway I don’t think you should ask gender neutrally since the women’s underthings universe is completely different from the one for dudes. Brassieres in particular are a nontrivial feat of structural engineering that have to make various technological and cost trade-offs to provide the best mix of comfort and support. I don’t wear them myself, but my lady friends tell me that you really have to shop around til you find a model that you like, then buy multiple units, and that they will probably be expensive.
My gender has an easier time of it. I just get the 9-packs of cheap white cotton ones at Target most of the time. The sizes run small so take that into consideration. The usual failure mode is that the elastic band around the top gradually detaches from the fabric underneath. If you’re frugal you can repair that with some stitches.[1] Later the fabric starts falling apart or getting holes. In principle you could patch it, but really, just throw the damn things away (compost bin should be fine as they are mostly cotton) and buy new ones. I probably somehow lose them more frequently than I wear them out.

The axe is better for making your own furniture. The word “hacker” supposedly originally referred to people who made furniture that way.
