Compared to just five years ago, RTW menswear has seen a renaissance in terms of selection of different "silhouettes" and more frequent product refresh cycles. A key ingredient of this renaissance is industry collaboration.
There are two types of collaboration - brand and production. The first type gets most of the press. This often means the pairing of a contemporary designer with a retailer. Witness this partial list of such menswear collaborations:
Gant's campus store in New Haven, CT is a mash-up of a defunct American trad retail storefront (Langrock's) with all three Gant lines - Gant, Gant Rugger and Gant by Michael Bastian.
The other type of collaboration is more behind the scenes and takes advantage of "Made in USA" to reinforce a heritage and/or authenticity branding message. Hence, the tapping of Brooklyn-based suitmaker Martin Greensfield by the likes of Band of Outsiders, Rag & Bone and Freemans Sporting Club.
