Would you like a black lace cocktail frock? I have one I got from an op-shop for a particular event. Its a wrap around style so it's quite forgiving for fit. Very well made - I think maybe originally a designer style, certainly quite high-end. You can have it for free if you want as it's just taking up space in my wardrobe and I don't think I'm going to wear it again. Was going to donate it once my local Vinnies starts accepting clothing donations again - they aren't at the moment as they are chockers.

Don't underestimate how good women in cocktail suits look either. If you wanted to wear pants that is.
