Hi all, I would really appreciate some help. Going to a posh theatre soon (not something I do a lot, hence no idea what to wear!) and I was thinking of a black dress that I will be getting lots of wear out. Up to £120 is fine provided it is good quality. I am 5'7 and 155 lbs, size 10-12 with a little mum tum. Either short dress or midi. Thank you so much!
