On the outside, it’s like you’re all about clothes. But underneath it all? It’s got to be Tt Mates, the new line of underpinnings by Tt Collection. The work of Los Angeles native Tiffany Saidnia (who learned a thing or two about basics and fit at Ella Moss/Splendid, Joe’s Jeans, and Imitation of Christ), the pieces are simply strong foundation garments but pack enough style to be worn on their own. Lounge in layers like the cozy long-sleeve crew and classic long (but not too long) leggings. Devise an entire getup around the subtly bohemian applique cami. And along with the slim tank, the body-skimming tube and cami dresses double as slips for just-right coverage when it comes to properly pulling off a sheer look. You’re not the type to let it all hang out. Available for preorder online at ttcollection.com.
