Sacai originally emerged from the Comme des Garcons stable. Designer Abe Chitose worked at Comme des Garçons and Junya Watanabe for 10 years before starting Sacai in 1999. She does lots of knitwear and I have a few pieces. She tends to focus on shoulder embellishments as well as frills and ruffles protruding from the hems of otherwise classic pieces. I have a beautiful little jumper with exaggerated shoulders and a lace up back with silk poking out through the lace. I love it - its really gorgeous.
