I bought two lovely dresses this weekend - a shirt dress from East which fits perfectly, feels great (tho it reminds me of something my great aunt used to wear), looks nice i hope (!) and a sundress from Matalan which is same size (I suppose you might expect a difference in sizing from these two shops).
The sundress is fine on the lower half but although I can do it up (it has a side zip)it is extremely tight on top (I have rather large boobs. Am size 16 top and size 14 bottom. Both dresses are size 16.
Any tricks of the trade to loosen it/ let it out a bit. It did make me think how do all those skinny women with enormous (fake?) boobs cope with normal dress sizes.
Should add that I am neither skinny or have fake boobs.
Other option is to try to loose a few pounds.
