I got these panties because I am currently pregnant and for those that don't know, your hips and butt seem to get bigger with pregnancy as well.  I usually wear a medium but when my husband pointed out I was showing a bit too much crack with my pre pregnancy underwear I decided it was time to upgrade to the next size.  I bought these based on the reviews, I like boy cut briefs in general.  These are very comfortable, nothing scratchy.  No tags which is a nice bonus.  I've washed them several times and they are holding up great.  There is also a good amount of space in between the leg holes... some boy cut briefs run a little narrow in that region giving you a big wedgie.  Overall I would recommend this product.
