can a lady wear a thong at the sundestin beach resort in destin florida?

There is no county or municipal regulation in this area that forbids wearing a thong while on the beach, so long as you are not actually revealing anything. I have never heard of a rule at Sundestin that forbids wearing one on the beach. However, the resort will probably require you to be “appropriately attired” in most areas, which may mean they will require a wrap or towel going to and from the beach.

Once you are off the beach, local businesses can and will throw you out for wearing a thong, so bring shorts.
