I wore these jeans when I was pregnant with my second daughter. When I was pregnant with her the under the belly jeans were popular; however they were new to me!
These are your typical blue jeans and I think good quality jeans. The price is pretty decent and you can sometimes catch sales at Motherhood Maternity.
They are comfortable; however my personal opinion is that the under the belly is more for when you are further along and your belly is bigger. I say this because it will keep the pants up easier. Even though I wore them further along in my pregnancy I was constantly pulling them up because they would keep falling down.
They wash well too. I did not notice any fading at all. They lasted very well throughout my pregnancy and through much wearing.
