The iconic Kitty flats we know and love, created by Charlotte Olympia Dellal, just got a rainbow-dose of color for spring. The London-based designer recently debuted a selection of limited-edition flats in six new brilliant hues at pop-up shops at Nordstrom at The Grove in L.A. and at the department store’s flagship in Seattle. The Italian-made shoes are crafted with ultra-soft suede and lined with leather, fronted by those two irresistible embroidered cat ears, and finished with a shiny gold heel.

“My original vision was to create a unique version of traditional men’s-style smoking slipper,” Dellal told InStyle.com, speaking about the Kitty flats which she first debuted 2011. “I wanted to translate a typically masculine design into something more feminine, delicate and flirty—like a cat! I turned the high-cut vamp into the shape of ears and instead of a monogram, ornamented a cat’s face.”The clever take sparked a feline frenzy, and it remains a must-have item on the lists of stars such as Emma Roberts, Beyoncé, and Jessica Alba, among others.
