hey ladies i have a wedding this weekend to attend and I had a question about wearing a chanel flap bag. i have a "hybrid" black flap from this season which i am pairing with a nice black bcbg dress for the wedding. my question is, does the chanel flap look more formal when worn long, with a single strap or shorter, with a double flap, so it's just under my arms? I am thinking that the shorter style makes it seem more casual than the longer single strap?? what do you think ladies??
