1/ Minimalist fashion: dress your lady in a minimalist outfit with appropriate apartment design. The title could be: Less is Often More.
2/ Lingerie contest: dress your lady in exciting lingerie with matching make-up and jewelry, like for a lingerie ad, possibly with apartment. (Could be a problem for lower level players though, so here is an altenative theme: sexy look that can include lingerie, with or wihout apartment design).
3/ Before and after: submit two looks, one showing your lady as just having got out of bed or starting to get dressed, and the other showing her as fully dressed up with make-up, ready to go to school, work, date, etc. This idea was inspired by Mel Keiser's page: http://www.melkeiser.com/becoming-mel.html
