Leg Avenue Women's Glow in The Dark Skeleton Bodysuit Halloween Costume

I'm concerned about size; i am 5'5" 104 pounds i wear a 00. is small small enough for me?

I'm 5 ft about 115 but have thicker legs (21") will the small fit or should i get a medium?

I am 5’1 and 145 pounds 36dd. what size should i get

I want to cut the sides open and/or potentially cut the back off and tie it back together or reattach it with straps. Does this seem possible?
