Very nice...
While dress-ups are not my favorite genre, it was refreshing to see one so well done. Graphics are well drawn, everything is crisp and clear, and it is well organized.
As a girl, it was nice to see a dress-up with a male model. Perhaps, to apease the majority (it would seem) you might want to consider making the option to choose gender at the start of your next dress-up game.
Overall, I enjoyed it, and I felt that you did a great job on it. I'm sure your girlfriend was very pleased.
