Vintage Blue: The color or wash is likely a faded, worn‑in or “vintage” blue tone. Possibly stone washed, acid wash, or a denim/light chambray look. Could be lighter in places (fading) to give a retro aesthetic.

Edition 1: Implies this may be the first in a numbered series, so possibly limited edition, maybe small batch or special fabric/treatment.

Probably casual or streetwear style, maybe loose / relaxed fit or drop shoulders.
