Lululemon Wunder Under Black size 10

Full length tag is ripped, and there isn’t a size dot. But I was assured these are a size ten There is no piling on the crotch area as shown. There is a loose thread however. There is some piling on the waist seam however, it could probably be removed with a razor but I don’t feel comfortable doing that. I’ve pictured it, it’s very minimal. There is some piling on the inside on the waistband seam, that is a little more aggressive but could probably be removed.
