77circa

77circa MEN'S LINE is a men's collection derived from 77circa, which had focused primarily on womenswear, and launched in 2020AW. Like the main brand, it is based on reconstructing USED garments, while offering PLAIN SWEAT, SHIRTS, DENIM, SLACKS, FISHERMAN SWEATER, and other items in a men's-oriented lineup. It continues to be featured on the official page for 2026SS and, separate from project lines such as O by O, presents clothing on the men's side.

77circa's ONE BY ONE (O by O) is a project line launched in 2021SS that, together with its supporters, donates part of its sales to animal welfare organizations and shelters. Its role differs from that of the main line, which focuses on reconstructing used garments, and 77circa MEN'S LINE, which handles menswear design. Through goods such as original-print T-shirts, long-sleeved shirts, pouches, and stickers, it extends the brand's philosophy into social contribution. The official online store also shows offerings for 2026SS.
