She might look at the Terry Bella short that has a mid-rise with wide waistband and elastic-free front yoke, http://www.teamestrogen.com/prodTY_610010.html

Also REI has the Novara Mezzo knickers with a non-binding waist band, http://www.rei.com/product/809715/no...-tights-womens

I have both and prefer the chamois in the Terry, but the others are fine as well.

I have some women's apparel from Aerotech Designs. They are a great value and well made. I would prefer a slightly higher rise in the back. Their waistbands are not too bad either.

Hope this helps,
