I know M&S bras get bad reviews on MN but for me, they work as I'm fairly small busted.
BUT- if there are any bra experts reading...
I've bought (online) and kept 2 of their basic push up T short bras.
But I find their sizing all over the place. I always buy online as I don't have many decent shops nearby other than John Lewis, so I buy a few sizes in the same style, online, to try.
I measure 28-29 under the bust and usually buy a 30D (in their Rosie range) which fits pretty well.
In the bra I bought this time, the 30 back was VERY tight. I had ordered the 32D as well, so kept that. However, the black one feels very tight, and when I have measured the band on it, it's only 25 inches. Even allowing for stretching it, you're not getting 7 more inches!
Some M&S and other brand bras in a 32 back are far too loose.
What's going on with their sizing?
