Help! I'm going to my other half's work summer party. It's on a boat (well 'ship') on the Thames, it's black tie. Other half is quite senior so I want to be smart. I'm 35, big curly hair, 5' 5' but the catch is I will have a 4 month old baby and do not really have any 'shape' - I'm currently a size 10/12 , my waist hasn't returned and I"m exclusively breast feeding so I need something I can easily access my boobs (to run off express a little at some point in the eve). I have no idea what will suit me. Any ideas?
