If it's rigged, you should be able to just wear it via the "add" button in your inventory. It should be noted that for rigged items, you need to check "With weights" in your viewer's mesh upload panel. You should find this option in the "Upload features" tab of that window. If doing that doesn't allow you to attach the dress and just wear it, the chances are you may have to rig it first.
