Comfy panties from Jockey.  They don't ride up, which can get uncomfortable with other cuts of underwear.  I wear this brand and cut all of the time.....my only complaint is that the location of the Jockey tag on the waist band often leads to the tag wearing thru the material, which leaves a little hole on the waist band.  Not a big deal, but they usually run around $20 for 3 undies.
