As a dark-skinned Roegdayn with fiery red hair I've had issues with deciding what color attire will actually suit me best. Many times the items that are searchable are only on pale Lalafel retainers, and they're always subject to the market ward lighting, which I like, but sometimes changes the real color of the item. Sometimes, the retainers don't have the items I'm currently looking for on display.

The only way to currently deal with this is to buy the item, equip it, and then resell it [which I've done several times] if I don't like it.

A better solution for 2.0 would be developing a dressing room which would allow you to preview the item you're equipping before you purchase it, along with other items, so you can get a good idea of how you would look before making a purchase.

Others games have this, including one that I play, and it is an enjoyable feature that both saves time and makes players happier.
