She’s got the athletic market covered with her New Balance line, and now, Heidi Klum is expanding her growing fashion empire with a new collection, HK, for Amazon.com. In the clip above, Klum mugs for the camera as models work her cute, strappy sandals, available online June 1. She gives us a sneak peek at her latest clothing collection — the dress she’s wearing is part of it! — as well. “It’s a mixture of beautiful things for the summer,” Klum tells PEOPLE. “Short little dresses, awesome tops.” The supermodel, a mom of four, says that while she loves high-fashion clothes, she appreciates a chic, comfy ensemble too. “I do normal things too like bringing my kids to school in the morning or just running thousands of different errands, and I don’t do that in a hot cocktail dress,” she jokes. “I always look for fun, easy pieces that are still fashionable.” Check out the clip above for more on Klum’s latest collection!
