I'm struggling to decide whether I should buy this Odd Molly shirt [[ http://cgi.ebay.co.uk/Gorgeous-Odd-Molly-Duvet-s-s-Blouse-218-Lilac-Size-4_W0QQitemZ110535400460QQca tegoryZ53159QQcmdZViewItemQQ_trksidZp4340.m263QQ_trkparmsZalgo%3DDLSL%252BSIC%26its%3DI%26itu%3DUCI% 252BIA%252BUA%252BIEW%252BFICS%252BUFI%26otn%3D20%26po%3D%26ps%3D63%26clkid%3D8407848696673675641 ]] As well as wondering whether it is a fashion faux pas or not (I really like it of course) I can't decide whether it is going to fit me. It is a "size 4" which is variously supposed to be a 14 or 16. I am an average 16. Any advice welcome!
