Matchy-matchy is having a moment, thanks to Heidi Klum's coordinated Tibi separates. We spotted the supermodel stepping out in NYC in Tibi's Spring '13 windowpane prints — now we want them too. Equal parts polished and playful, this is the perfect outfit to take you from a casual workday to drinks or dinner. Follow Heidi's lead and add a bright tote and classic pumps to further the styled-sophisticate vibe. Just be warned — Tibi's Spring lineup is flying off the shelves; act fast to get a piece of it, and shop our editors' picks for ways to re-create the look. Everything you need is below!
