I'm going back to the office after mat leave soon. I've just cleared out all my maternity stuff and stuff that's got too scruffy and realised there's nothing left! I'm in a professional job. People tend to dress smartly but not in suits, though I'll need one for occasional use. Where should I go to refresh my work wardrobe without breaking the post-mat-leave bank? I'm a size 12 and tall. Thanks!
