Here's a feature highlight for the day for you: the Visual Outfit Browser, originally developed by Linden Lab for their official viewer. It's been in Firestorm since our 5.0.1 release.
This feature allows you to add snapshots to your outfits in the Outfit Gallery tab so you don't have to remember what they look like. You are charged L$10 per photo, just like any photo upload.
For more info, you can see the brief description of the outfit gallery on the Firestorm wiki or check out Inara Pey's explanation from back when it was released in the SL viewer.
I'd probably use this if it didn't cost 10L for each upload, especially when I'm skint
