Yet another dress from Kate Middleton‘s wardrobe has completely sold out. The Duchess of Cambridge looked pretty in the Tory Burch “Paulina” dress for her appearance at the first event on the Royal Tour, a New Zealand playdate. Middleton, along with Prince William and Prince George (who wore adorable overalls, in case you missed it, paid a visit to Wellington’s Government House to meet with new mothers and their babies at an event for the Plunket Society.

The multi-tasking mom looked perfectly put together in the classic-meets-eclectic frock with a graphic, open knit and textural fringe. The casual-yet-chic dress was a great selection for the occasion, featuring an all-over lacy dot pattern in black and ivory, with a ladylike silhouette and tassel-like trim. Within hours of Middleton wearing the slightly flared Tory Burch frock—priced at $395—it was already our of stock on the designer’s e-commerce site (and everywhere else we looked). Before the photos were even posted online, royal fashion followers were sharing the details of the dress on Twitter, resulting in the quick sell out. This is not the first time Middleton has caused a fashion frenzy, and it certainly won’t be the last.
