Nope, it’s not another diffusion line (although one of those does exist as well). Anna Sui is celebrating its 30th anniversary this year with the launch of a first-ever retrospective book. In honor of such a milestone, Sui and Anthropologie, who have a longstanding relationship, got a little anthropological and selected three iconic Anna Sui dresses to resurrect and sell exclusively at Anthropologie stores. The dresses are each from a past collection–Fall 2005, Spring 2001 and Spring 2007 to be exact–and were key looks from their respective seasons.

It’s not often that a designer reissues pieces from old collections, but when they do, it’s special. Along with Balenciaga, YSL, and Chanel, a recent example is last year’s Betsey Johnson archive at Opening Ceremony, where the designer boutique resurrected 35 pieces for that brand’s 30th anniversary. Betsey’s collection felt more like vintage, without the “previously-owned” feel. Many of the pieces recalled the era they came from like, say, the ’80s. Sui’s, however, feels more timeless.

We think Sui is particularly well-suited to a project like this because her designs are never overly-trendy. The dresses are available now at Anthropologie.com. The book will be available in early November, looking something like this:
