Parents are invited to my eldest's leavers' ball this summer and I don't really know what to wear. I've asked ChatGPT and it wanted to dress me like a bridesmaid, so I'm hoping that I'll get better style advice on here. My husband will be wearing black tie, so I want something that will 'match' him. I'm 5'4", size 14, big boobs and the Romantic Kibbe body type. I'm also an autumn. I would love something that skims my tummy and is modest. It's a classy school! Budget up to £150. Thanks.
