I'm due to return from mat leave in a few weeks and have no idea how to dress for the office anymore. Slightly bigger than I was before & more of a tummy than I was used to dressing for (now UK size 12). Doesn't need to be particularly smart but would like some differentiation between my work wardrobe & my 'mum wardrobe' that I live in the rest of the time. Ideally not too pricey & layers to allow for dealing with the heating up/down battles in the office. What workwear items do you love/feel good in?
