Nomine has tons of items in the lucky chair right now. Gowns, lingerie, sexy ensembles, and my favorite, the babydoll dress.
I'm not even sure of how many of these cute little dresses are in the chairs, but I got these four so far and I know that there are more I have not won. The time is 10 minutes between letters so not too long (but of course you can join an awesome group like Lucky Chair Stalkers to get those letters moving faster ;D).
