Mary Kate and Ashley Olsen’s StyleMint–which is like JewelMint, but for t-shirts–launches July 1. In a lead up to the debut, StyleMint has put together an animated “fashion statement” which tracks the history of the t-shirt, featuring iconic images from era’s past.

Why is StyleMint so significant? Well, the Olsens aren’t just curating this t-shirt of the month boutique like Sienna Miller and Kate Bosworth have done for JewelMint, they’ve partnered with the company. BeachMint, the Santa Monica-based tech startup, just raised $23.5 million at a rumored $150 million valuation. Which means, if this venture is successful, the Olsens stand to make a good chunk of cash.

We’ve already signed here up for StyleMint. Are you going to?
