Am a 35 year old size 14 with a wardrobe entirely made up of scruffy jeans and boring work outfits. Am having a childfree weekend for the 1st time in aeons next weekend staying with SIL in London. She has just mailed me to say that I must bring some heels and a funky / glammy outfit. Have neither and not much dosh to spend. What should I wear / buy that isn't too expensive but makes me look a bit more special than my tired everyday stuff? Help me oh wise Mumsnetters....
