I've held on to a denim jacket for years after going up a dress size because it's such a beautiful shape, and I hoped that I'd eventually be able to wear it again.
I've lost some of that weight, and the jacket now fits ok across the shoulders and back.
Whilst I'd never fasten the buttons on a denim jacket (or any jacket really), I've always felt like size-wise it should look as if it could be done up or within an inch or two of that. The edges of this jacket now go just past the nipples, so about a 4-5 inch gap. I thinks it looks ok, just don't want it to look like I'm wearing a jacket that is too small. What do you think? Thank you
