“I bought a few different kinds of snug undies and found that the high-waisted swim brief from Blair catalogue to be by far the best for me in terms of comfort and snugness to keep the dilator in place. I had bought a couple of different sizes due to customer reviews that indicated they run large, and indeed the ones that fit are one size less than my normal size. Here is the link, fyi: http://www.blair.com/p/high-waisted-swim-brief/73603.uts (Check the homepage for savings codes, which they often have – either free shipping or a percentage off.) I’ve now bought several additional since they work so well, and the feel like undies.”
