I finally received the long boyfriend blazer (http://www.jcrew.com/AST/Browse/WomenBrowse/Women_Shop_By_Category/jacketsblazers/jacketsblazers/PRDOVR~19197/99101843971/ENE~1+2+3+22+4294967294+20~~~0~15~all~mode+matchallany~~~~~long%20boyfriend%20blazer/19197.jsp), which had been backordered for awhile. I am disappointed! It is GIGANTIC! I ordered a 0, which is my size in pretty much all brands, but it is totally voluminous. I know it's not supposed to be fitted because it's "boyfriend" style, but it's baggy as opposed to boyfriendy. Sigh. Oh well.
Same thing happened to me. I loooove this jacket but the zero was gigantic. So, I saved some money by going to urban and getting their bf blazer, taking it to my tailor to add some buttons.
