AUROLAwomens Power Leggings for Women Leggings

Will xs be tight if I’m 5’6 tall and weigh 91 pounds? I’m looking for something that fits me right and heard this brand did.

Do these roll down on the waist ?

Will these be coming in the intensify colors? This fabric is way more durable, I prefer these and would love to buy more colors.

Are these long? I am just under 5 Foot.
