Style and beauty...looks round in amazement, not somewhere I come on Mumsnet, but I have a challenge for you clued in people. I am an academic in the Engineering department of a university. I'm going to the student ball and I need something to wear. I will literally be 30 years older than any other woman there (all the female students are in their late teens/ early 20's, I am in my mid 50's). I need a dress suitable for a ball (with ceilidh dancing so probably short rather than long), that is social media proof - no low necklines, no splits, no risk of dodgy pictures, less than £100 and suitable for a fairly well proportioned size 16, medium height woman. Help!!
