These lightweight body stockings come without straps. You can either add your own straps if you plan to wear under a top with more coverage, or attach to your costumes using hooks. They will also tuck under a bra band if it's tight enough to keep the stocking in place. They are designed to provide a little more coverage for those of us who don't like to completely bare our tummies. They will not reshape you or 'suck you in'. The gusset is closed but as these are so lightweight they can easily be tucked to one side when the need arises. They are free size and very stretchy.
