I noticed on K Can Shop's thread today about her black blazer (http://youlookfab.com/welookfa.....ket-opinon) you commented that the jacket was too tight when done up and there were suggestions to try a size up.

Do blazers always have to be able to do up? My new Danier black leather blazer just barely zips up and I will always wear it undone so didn't worry about that. Just curious.
