I’m starting a new job at the beginning of January after being on maternity leave since Sept 2018. I put a lot of weight on during pregnancy and none of my old work clothes anywhere near fit anymore. The dress code is casual but I’d prefer to keep it on the smart side but no need for full suits/business attire. Currently a size 16, 5ft 6. I really want to look/feel confident and we’ll presented. Please help!
