Am off to a meal/cabaret/disco thing on saturday night with a group of friends who are all younger, thinner and more stylish than I am and need something fast! Am thinking a dress but all things considered. Am 5ft 3 size 12/14 - have put some weight since Christmas!!, fat tummy, don't like my knees so nothing too short, am 46 and as cheap as possible - pref somewhere I can try on
