>> Mary Katrantzou's 10-piece capsule for Topshop hits stores on Feb. 17, exactly one week from today. Now, thanks to UK Vogue, the collection's entire assortment has been revealed — and it doesn't disappoint. The collection features easy shapes — structured dresses, clean-lined tops, and slim trousers — covered from top to tail in a wild mix of Katrantzou's pretty prints. Priced from $63 to $550, they're just the thing to kick-start Spring.

Mary Katranzou's graphic print dresses have taken the fashion crowd by storm, so you can imagine our excitement when the designer announced a collaboration with Topshop. The collection doesn't drop in store until February, but Susie from Style Bubble was able to get a peek at it. Feast your eyes on one of the designs, seen here in the middle, at Topshop's press day. As you can see, the design is nearly identical to her namesake collection but without the heft price tag. Her original designs are priced around $4,500 for a dress, but the one you see here will cost a lot less. Pricing and details on the exact release date are to be determined, but expect these to sell out fast. The most stylish celebrities have been spotted in them — think Keira Knightley, Alexa Chung, and Leelee Sobieski — and click our slideshow to see which prints these A-listers are wearing.

Spring is blooming at Topshop. Both Richard Nicoll and Mary Katrantzou's new Spring collections for the British mass retailer debut this week. Shall we review?

Then there's Greek designer Mary Katrantzou, who delivers leotards and t-shirt dresses with simple cuts but bold prints. Pick your favorites now.
