Check out Official March Themes thread.... and join in the fun. Otherwise... bikini bottoms a cover up for the day and at night very sexy dresses that she wouldn't dare wear at home are exactly in order at TTR.
Some lingerie for lingerie night , a red dress, and a white dress is a good start, the shorter the better , you will understand when you get there.
Since it's your first time, I'm gonna say whatever she feels drop dead sexy in. Anything goes, everybody has a different idea of what is comfortable for them and anythingis acceptable.
Sexy shoes, outfits for theme nights, bikini bottoms, cover ups, anything that ....If she try's it on in the store, and it makes her feel like a slut, or any outfit that you would never wear in your hometown or let your family see! If any of these conditions apply, it's perfect!!! Lol There is a list somewhere in these forums about what to pack. I'm sure one of the lovely ladies (Karen) will forward it when she sees your post.
