Depends if options responsble are avaible to moders (after last Addons nerf) -but for example in Secret World im using a "Wardrobe" addons that show you how all various clothing look on your character.Thanks! Perhaps a UI addon will release for this feature.
There's a dispute amongst players as to whether or not this should be added. I personally support it but the argument against is that it would let elitist group leaders quickly inspect a player and deny them entry to a group if their gear wasn't a high enough level.
