Olga Tricot Half Pant Brief —
I think the fit and feel of these panties are exceptional. Even for ladies with a "bubble butt" they don't ride and they stay put even when you are active. About the only negative is that they can be a bit pricey, but they are a good value for the money. I think one reason they fit so well is the back seam that corresponds to the natural cleft of the behind. Also, they don't show panty lines even when you wear tight dress pants and skirts.
