From the Travel Collection, the luxurious and unique Oroblu One And Only sheer tights are designed to offer an innovative solution to choosing the right size. They're made from an ultra-stretch yarn that's designed to fit everyone! (We say 5'0"-5'11" to be on the safe side, but there's no official size chart as such.) The elasticity comes from a combination of the unique yarn and the knitting technique, which help them to adapt to different silhouettes. They're sheer to waist, with a comfort waistband, flat seams and a cotton gusset.
