I loved the fabric and initial fit, but the panties stretched quickly (within an hour or so) and continuously rolled down. Since I had worn them, I was unable to return them to Amazon. I received an email from the seller asking for a favorable product review and what they could do to resolve any issues. I wanted to love these underwear, so I responded to the seller regarding the stretching and asked for advice on sizing. They never replied, evwn after a 2nd email.  I'd like to try a size medium (instead of the initial large) and see if that resolves the stretching and rolling issues,  but frankly, I am disappointed with the seller and therefore do not wish to give them any more of my money. My advice to the seller -- (1) don't ask for concerns/customer feedback and fail to respond; (2) don't demand a favorable review; (3) don't say you stand by your product if, in reality, you do not. Disappointed.
My advice to customers -- consider ordering a size down, which may (or may not) prevent fabric stretching to the point where it becomes baggy. If you have a tummy pooch, these panties will roll down and give you the muffin top that they are designed to prevent. Girls with flat tummies will like these.
