BESFXXK

BESFXXK

By Jae-hyuk Lim & Bona Kim · Seoul

One garment, two ways — hybrid tailoring from the London–Paris runways

Founded by the design duo Jae-hyuk Lim and Bona Kim, BESFXXK shows on the London and Paris fashion week circuit. The label deconstructs tailoring into hybrid, functional high fashion — half a trench coat fused with a technical windbreaker — so one garment can be styled in two or more ways.
