I, along with a few others will be wearing our sheer suits. Technically, is it a suit when it's sheer? LOL
We went last November and didn't see a majority, but probably 20% of the women were. By day 3 my wife was joining the thong crew and I enjoyed every minute of it!
You should definitely bring them in case you want to wear them. I admire women who do it! Go girl! ~Jill~
