HONENNA Women's Control Top High Elastic Soft Opaque Pantyhose Tights (Green, L/XL)

Is the Navy blue light in color. Is it actually a nice blue color?

My daughter is 5’6” and weighs 130 lbs. What size should I order?

Would these tights be too warm for my 12 y.o. son to wear under his jeans? Could he wear them as leggings just around the house?

where are these made?
