I’ve been invited to an event at an extremely fancy London venue later this summer. It’s so beyond my comfort zone and I know that other people going will be slim, elegant and wearing expensive outfits. (I’m normally in primark jeans and Lidl trainers…) I’m 50 , short and ( having lost 2 stone) now a size 14… and I’ve no confidence with dressing up. I’ve not got a big budget - max £100? So I need some help. Would a dress agency be a good start?
