I'm a 38E, and have only one bra that I can bear to wear in this weather. It is a racer back pull on vbra made of breathable (wicking?) fabric which means that it is not too sweaty around the band.
However, it is quite high cut, and the straps are very visible under most of my clothes ( v or scoop neck dresses in this weather). It's OK under a shirt, but I really would prefer to wear dresses when it's hot. It's the bit just near the collarbone that shows.
Does a non-racer back version even exist? Is the racer back necessary for support when one is a larger size? I couldn't even think of underwiring,and I'm wearing it more for modesty than flatteringness! It's the wickiness that I so like about it, but all the sports type bras I've seen are racer back.
Any help much appreciated.
