An in-game UI that let you try on every piece of glam and how to get them

While we're at it, can we also have this for retainers? It's a pain in the ass to dress female retainers on a male character or male retainers on a female character, since you can't preview how a glamour piece will look on them before you buy or craft it.

That's even less likely to happen. You may as well use one of those websites. Every piece of glam is catalogued somewhere. You could also make an alt to look at stuff on the market.
