Rant: tight sizing. If you're tall and long-legged, you have to buy the L/XL size, which are then too loose on the top and creep down. If you get ones that fit your hips and butt, then, the crotch is somewhere around your knees (passed along by my daughter, the 5'10inch skater with the 35 inch inseam who wears size 2 jeans ...) With my other kid, who has a similar narrow hip and disproportionately long leg problem but is only 5'3, to get them long enough in the leg, the waist band ends up somewhere around the middle of her chest, where it again proceeds to creep slowly south through practice. Why can't them make tights in "tall" to accommodate tall people?
Yes, we're tried to buy the smaller sizes and stretch them up ... doesn't work for longer than a single dance test ...
