I mostly work from home but I’m going to an in-person training course for a week soon and I’m really worried I have nothing to wear. I need to lose weight and have been holding off buying things till then. I’m about 5’6”, size 14, weight fairly evenly spread but biggish bust so things with buttons don’t work. Dress code is relaxed but there’ll be people there I need to network with so thinking smart casual. Any suggestions?
