Commando Response: Our ultimate matte opaque tights are 70 denier which gives a very opaque look and luxurious feel. The vast majority of customers prefer this weight for tights so a lighter
tight would be a personal preference. Our sizing chart is very accurate and the customer's 5"3" height would suggest the large size you purchased is too big. This would
certainly explain why they would be slipping. When wearing the correct size our waistband is super-comfortable and lays flat against the body.

Commando does fit testing on all its products to ensure they fit women of all shapes and sizes. While we do our best to provide a size chart that will accurately reflect the fit for the majority of customers and seldom receive complaints, everyone's body is different. A size medium should have plenty of length in the leg for someone who is 5'8".
