Real Boys In The Clothes (Ages 10–16)
Calibrated specifically for how boys actually live and move, eliminating sizing guesswork.
Why dedicated boys sizing matters: Standard menswear smalls have shoulders that are too wide and body lengths that swallow a boy’s frame. Joy Ryder drafts garments specifically for boys aged 10 to 16 with real boys in the clothes — like Jake: 14, 165cm, wearing size 14 (AU M).
Proportioned shoulders, comfortable sleeve drops, and vertical comfort allowances ensure pieces drape cleanly with an authentic relaxed silhouette today, while naturally accommodating growth across seasons.
True-to-fit relaxed streetwear. If your boy is in between sizes or growing quickly, size up one size for two full seasons of wear.
