I bought some Boden culottes in their sale, but have no idea what to wear with them, in the way of shoes. They are longer than I realised (3 inches above ankles, though I'm 5'9"), I need them for work (teaching, meaning I'm on my feet all day), so footwear needs to be comfortable. I'm not sure whether they look ok with flats or not. They look good with heels, but I can't wear heels all day. Boots, maybe? I don't want to have to buy more shoes as my teacher's salary doesn't allow a lot of expense.Dress code at my (private) school means fairly formal look). I would appreciate some help for a fashion moron - thank you!
