When we think about Jennifer Lopez's style, we don't think comfy T-shirts. But for some reason (ka-ching!), J.Lo has teamed up with L.A.-based entrepreneur Brian Lee to launch Teeology, an online store of limited-edition luxury T-shirts. Here's how it works: The site presents members with a selection of printed T-shirts, which members then get to vote on. As founder and curator, J.Lo will help decide which designs go out to members to vote on. The winning designs then go into production. Basic tees cost $20, while limited-edition styles start at $29.
