I'm wearing this outfit to a wedding at the weekend but I literally don't have a clue how to accessorise it. I have some black Mary Jane shoes which look good with it (the outfit is black/white spots) but I'm stuck on headwear, bag and a necklace. I'm a size 22, 5ft 4 and barrel shaped and I always feel like I've been in a dressing up box if I try to look elegant. Any advice is gratefully received!
