I haven't worn a matte polish in a while, so I picked OPI La Paz-itvely Hot.
This is probably my favorite OPI matte. Unlike the others, it has some shimmer to it. I love these because they dry so fast! They do tend to stain though. OPI says not to use a base coat with these, but I used Nail Envy matte and it seems to work fine. There have been some complaints on these regarding the wear time, but it really doesn't bother me since I change my polish so often anyway. The OPI Suedes seem to be more durable. I currently own Here Today Aragon Tomorrow, Lincoln Park After Dark, and Suzi Skis in the Pyrenees. I know they've been discontinued, but they're on Amazon and eBay.
Here it is without the flash.
