Hello and welcome to basenotes!
As Shycat stated, the wardrobe is a link to a virtual display of the various fragrances you own. Adding them can be a bit of a pain, since each one you own must be added one at a time, manually. It is worth it once you get them all in there because it's a good way to keep track of what you own, want, are trying to sell, and are looking to sniff.
As for your profile, go to the User CP link and on the left side you'll see a number of things you may edit. Have at it!
Enjoy!
