Really lusting over all the delicious pastel trench coats around this spring particularly the ones with a fuller skirt to them iykwim. Thing is a) I'm a size 18 / 20 hourglass b) my two small boys make trips to the shops to try them horrendous ... So before I commit too much time and emotional energy on this project, please tell me trench on a plus sized bod - yay or nay?
