Per the title - we're having a party for his 50th. Husband has lots of cool fashion-y mates, none of whom look or dress or act like 50 year old. It's a party in quite a nice bar in central London. I have no idea what to wear. I'm 5'5", big boobs, size 12 (14 top for boobs but not for waist/shoulders). OK legs, not amazing but not bad either. Triceps a bit floppy but otherwise ok arms and shoulders. Hourglass-ish figure, perimenopause has given me a little tummy but it's less.visible and more just I don't like things being tight on my waist. I generally look fairly young for my age. I like jewel colours, neutrals or black, no pastels. My usual style is barrel leg jeans with oversized shirt, or wide leg trousers with fitted blouse. I dont often wear dresses or skirts although I dont dislike them. I want to dress up but also look cool and simultaneously elegant. Brands I like are Whistles, Massimo Dutti, Ralph Lauren, Max Mara, Reiss, Me & Em, (but my budget is definitely high street!). Any ideas at all welcome, I've not got a clue!
