What diaper bag/backpack do you or have you used?

Tiffany • Had my first on April 9th 2015.
We have the fisher price backpack diaper bag for the husband. But just in case I were out somewhere nice like church and I don't want this big ol backpack to clash my look. I am not looking to spend over $100. Not interested in designer bags. I am interested in affordable and very convenient! Lots of pockets and apace and organization!
