This is the small bag ($35), and the petite bag is a bit smaller. I wouldn't necessarily call it small, because you could probably fit a good bit of makeup in there. There's definitely enough room for all of the products you could wear in a day, a set of lashes and glue for the evening, and a bolder lip combo.
My only issue is keeping this clean. The fabric is 100% cotton. You know how things get--a random white bag rolling around in your purse is liable to get dirty. But since it's only cotton, I figure a good wash in the sink (or maybe the washing machine) shouldn't hurt.
All six bags will be available on August 23, 2012 exclusively at MAC Stores and online.
