The ties on the sides help you adjust it to optimal fit, and the style itself is great. The beads and ties soup up a pretty simple style, while the subtle lacy overlay does the same. Side note: the lacy overlay will probably fray if you spend a lot of time sitting on the side of a pool. (I wear small/5 size underwear and the medium fits great -- covers everything it needs to cover without looking like a granny panty.) Get it with the accompanying top for a great combo. My bf loves it.
