Does underwear matter?
Yes it does!
You're going to want to wear brief, boy cut or standard bikini style underwear with your pads. It's best if they have a snug fit and are made of a natural fiber wit a little bit of stretch.
If your underwear creeps where it shouldn't when you're not wearing a pad, that's a bad sign about how it will behave when you do have a pad in place. This can happen because the narrowest part of the crotch is too far back, and it may pull the pad further back than you want it. If this is the only type of underwear you have, you can compensate for the problem by wearing pads that are longer in the front.
High Cut
These should be fine as long as they fit well and are made of sturdy material, but you can't rely on the contour of this style to keep pads in place.
Bikini
Standard bikinis work better than high cuts because they have more contour.
With bikini style underwear, you may be able to get away with pads that are narrower than the standard 2 3/4 inches, as bikini crotches average closer to 2 1/2 inches wide.
Cotton or hemp briefs.
Never underestimate the power of good, sturdy briefs. Their crotch width is usually smack in the middle of average and they have ample contour to keep your pads in place.
Classic Hipsters and Barely There
These undies may be too narrow to work with most of the pads that I make, although people have found them compatible with the mini contoured backup and I can make the other pieces extra skinny for you. If you're really a minimalist though, you may prefer to go wingless. A safety pin will keep wingless pads from falling into the toilet.
Custom Narrow pads
Slippery, satin, silky, synthetic / baggy or old with worn out elastic.
Wear slippery, thin materials and baggy underwear at your own risk. If you do wear them, you'll need bigger pads with flared ends to compensate for any shifting, and you'll need a good textured backing material like synthetic fleece or corduroy.
Hat tip to Bruce, A. H., Fogg, G. J., Diedling, F. J. and Hammons, J. L. for some of the crotch widths. http://www.patentstorm.us/patents/6604609.html
