I don't know what that style with the zipper is called (I usually see them with buttons -- I've only seen the zipper on short coats at outlets) but if it helps regarding your question on age group at the top -- I'm in my 20's and have one, my mother (50s) has one, my neighbor and her daughter (20s, 40s) have one...it's a staple at any age. [emoji4] Neiman Marcus lets you use the "dollar off" event gift cards towards them, and
Nordstrom has them (button version, beige) on sale this week, but those are the only sales on the shorter quilted jackets I've seen. The Burberry boutique had short quilted jackets still full price today.
