and I haven't got a clue where to start!! The party is for a 40th wedding anniversary. I haven't been to a party for such a long time I haven't got a clue what to wear......jeans and a top? A dress? Skirt? 
I have a nice dress from Monsoon that I wore to a wedding last year but I have a feeling it's too weddingy IYSWIM.
I'm 30, size 18/20 depending on the shop. Large of nork (G cup). I'm in proportion (i.e big all over!). I don't suit a high neck or anything too girly/floral. Can anyone point me in the right direction? Next or Dorothy Perkins kind of prices.
