I have so many thongs sometimes it hard to choose. For everyday wear it is often what ever is at the top of the drawer. For special events I will either match the thong with the outfit I am wearing. For example a blue suit equals a blue thong. A night out will have me reaching for a more exotic thong (sheer, lacy, bulge enhancing, etc.). There are times I will have my partner choose the thong I wear. For beach or pool time it will depend on where I am, who I am with and how I am feeling.
