During her studies, she managed to sell some of her prints to Bill Blass. Graduating from her bachelor course in 2005, Katrantzou switched her focus from prints for interiors to fashion prints. Whilst collaborating with Sophia Kokosalaki in 2006, she built up a portfolio for the Central Saint Martins master's fashion textiles course. In February 2008, Katrantzou opened the Saint Martins MA Fashion show at London Fashion Week. Her collection was nominated for the Harrods and the L‘Oreal Professional Award. Katrantzou's graduating show in 2008 mapped out her signature style. It was themed around trompe l'oeil prints of oversized jewellery featured on jersey-bonded dresses. These pieces created the illusion of wearing giant neckpieces that would be too heavy in reality. She also designed jewellery made out of wood and metal that were exact replicas of the prints. Katrantzou's first Prêt-à-porter collection was shown at the autumn/winter London Fashion Week in 2008. She was awarded NEWGEN sponsorship from the British Fashion Council for six seasons. Katrantzou's first ready-to-wear collection for Autumn/Winter 2009 debuted at London Fashion Week in February 2009, with the support of the BFC and the New Gen scheme. Despite a small collection of nine dresses, Katrantzou picked up 15 stockists including Browns, Joyce and Colette. The designer achieved show status the following season, in Autumn/Winter 2009. For her spring/summer 2011 collection Ceci n’est pas une chambre, a title inspired by Rene Magritte’s Ceci n’est pas une pipe, she challenged the viewer by printing on her designs fragments of images borrowed from old issues of Architectural Digest and World of Interiors. As she worked with volume, depth and perspective, the clothes acquired an engaging three-dimensional quality. "With digital printing you get that precision engineering where everything is marked around the body in a perfect way." Her collections are now sold in over 200 fashion shops, including Selfridges, Harvey Nichols, Barneys, Neiman Marcus, Colette, 10 Corso Como, Joyce, Luisa via roma, Mytheresa, Hiphunters, Stylebop, Opening Ceremony and Net a Porter, and in 47 countries. A collection for Topshop launched for London Fashion Week autumn/winter 2010 and was available in shops in February 2011 and sold out within the first few days of its release. Katrantzou's work has appeared in publications including Vogue, Dazed & Confused, and Grazia. She is one of the designers of. February 2012 saw the release of her collaboration with Longchamp creating a capsule collection of bags and totes. To promote them Vogue Japan gave away a plastic card case with Katrantzou's prints with their May issue. Three prints featured in this collaboration over several different shapes and sizes. In April 2014, Katrantzou announced she would be working with Adidas 'for the foreseeable future', both clothing and footwear. Katrantzou sold a minority stake in her business to Yu Capital, the investment division of Hong Kong-based Yu Holdings, in October 2017. The terms of the deal were not disclosed, but it was said to have been part of Yu Holdings' founder and chief executive Wendy Yu's "wider plan to act as bridge for Western brands targeting Chinese consumers."
