Ahh, sorry to hear the Women’s Gunner Jacket (Amarr) was sold out. Also some of those items on your list haven’t been released yet.
I’m also collecting Apparel Items for both Male and Female, been doing it for quite a while now and am getting very close to having all previously released items. I use a 3rd party Market site to check the Market every day as well as log in to check Public Contracts and the in-game Market (some Apparel Items won’t be listed in 3rd party sites).
Anyway, I didn’t think about posting a WTB thread like you did, seems like a good idea. As for the Market, just gotta keep checking and eventually some of those items will become available.
