Well I went to get measured at M&S on friday afternoon, and the lady told me that I shouldn't be wearing underwired bras under any circumstances as they are supposed to eat way at your flesh while your breasts are growing. I don't know how true this is, so I have ditched my underwireds now in favour of some nice t-shirt non-wired lightly padded bras. (A lot of non-wired bras are really ugly and too high up at the front) My favourite new t-shirt bra is from BHS. It is nice and low cut at the front so it can be worn with low cut tops (we must take advantage of our new assets!). It is lovely and soft and was £12.
