Brett Westfall, designer for the louche L.A. collection Unholy Matrimony, isn't wooed by the zeitgeist -- you won't see him spinning out "Mad Men"-style suits or preppy sweaters any time soon.

The former co-owner of the Comme des Garçons guerrilla store downtown -- who now co-owns the Case Study Space menswear boutique in L.A. --  is a student of Japanese conceptual fashion, which he mires in a signature stew of punk-rock street wear.

Westfall's spring menswear collection, dubbed "Moon," feels particularly anti-commercial. Defined by long, over-sized trenches, raw-edged jackets and "anti" pants including distressed (ravaged, actually) cropped jeans and saggy drop-crotch pants, the collection feels fit for a post-apocalyptic wasteland.

The line's color palette — gray, olive green and black — heightens its militaristic vibe, as do subtle details including raw, unhemmed edges and jacket elbows tailored into mean little points that jut off the arm.

For the less daring, the collection boasts a long, heavy-metal tank top and a few graphic T-shirts -- one emblazoned with a graphic of a moon, and another depicting a skeletal rib cage festooned with colorful flowers and mushrooms.

Prices for the collection, which is available at Case Study Space and its online store, range from just over $100 for tees to around $475 for long coats.
