Dd needs a suit to wear occasionally at school (among other more casual clothes) and hopefully for university/job interviews. We thought maybe a navy suit with blazer, skirt (roughly knee length) and trousers (obviously not at same time) would be a flexible basis for the more formal days and can be worn individually with more casual tops etc. She is size 8 (lucky) and about 5'4". It doesn't have to be navy but ideally plain and preferably not black. She is hoping to do medicine so there will be interviews. Something which will not date too quickly, ideally not dry clean/ too expensive but not an obviously cheap purchase. Not too tight fitting around the top of the legs for the trousers. Ideally a physical shop (in SE) where we could possibly in a few months try it on rather than online. I am jeans and t-shirt person so totally useless in this area. Does anyone have any recommendations?
