There are long vertical seams on the outer hip area that run the length (top to bottom) of the panties. The seams face inward (of course) and the material is so excessive along the seam they leave welts (deep indents) on my daughter's hips and outer upper leg. They were hurting her so she pulled her pants open to show me the welts. I threw that pair in the trash thinking they were faulty. No such luck! She put another pair on the next day and the same thing happened. I should have saved the packaging so I could return them.
