I just searched this page to see if anyone had mentioned this subreddit. It is really useful. Follow the measurement guide carefully and look at recommendations of brands. I did so, ordered four styles, and had 2 solid wins, 1 ok, and one 'depends on the day'. That's way better than average.

For discussions of price in this thread, I consider a good bra a worthwhile luxury and will pay up to $100. For most of the bras I bought using the reddit guidance, I paid about $67 on sale. I will not pay more than $100 at this point; that just doesn't fit my priorities. Double my salary and I'd consider it.
