As above, looking for recommendations please. I like the no adjustable straps or clips very elastic pull on type with a racer back. Local running shops don't stock a huge range and I'm loath to just mail order by chance and hope I find a good one. Main problem I have is most of the ones I try are too long - the elasticated bottom band is often way too low. I used to like the Nike ones but now they seem too compressing and not elastic enough - I'm maybe between two sizes but the medium restricts my breathing and the large feels loose on... I also like vests with built in bra-tops but the same problem applies - my boobs are nowhere near the bottom of my rib cage thank you very much!
