Heidi Klum sports underwear as outwear

We applauded Heidi Klum for her micro-mini, slash cut ensemble with sequins in abundance last month and she returns this week for an appearance on The Tonight Show With Jay Leno, to further fuel our envy in a figure-hugging LBD. Heidi's knee-length number with curve-sculpting, corset detailing, belonging to the latest Thomas Wylde collection, is a distinct nod towards Fetish Fashion and follows the current trend for underwear as outerwear. Sex in fashion manifests itself in an incalculable number of ways this season and we love Heidi's (or rather, Thomas Wydle's) subtle yet seductive interpretation. Glance over our favourite, fetish vestments for some inspiration on how to carry of this trend in style; more sass than smut. We just need our very own pair of grey, suede Louboutins like Ms. Klum's now!
