I'm worrying about my back-to-the-office wardrobe. I've bought this top, and I think it goes ok with some tailored black trousers I already have, but wondering if I can pair it with a skirt too. I have tried it with a semi-flared a-line mid-length black skirt and couldn't decide. I'm thinking of buying a straight midi-length skirt as I don't currently own one- not sure about colour. Any tips from people who instinctively know what goes with what would be appreciated!
