Men's Grateful Dead Lined Plaid Jacket - Black/White

Owners report James Perse's numeric sizing (0=XS up to 5=XXL) runs true to size, with a deliberately relaxed, California-casual cut rather than a slim one.

Reviewers and sizing guides agree the numbered sizing maps predictably to standard sizes and stays consistent across tees, tanks, long sleeves, and sweats — one long-term owner wears the same size 1 across every James Perse product she owns. The caveat owners flag is that the house cut is intentionally roomy: tees and sweats read slightly relaxed at your true size, so people wanting a trim fit sometimes size down, while button-ups and polos can wear looser than the marked size suggests. On the women's side, fitted jersey pieces are the exception — reviewers note the skinny and fitted styles run small, and pants are cut long.

Sizing advice: Take your usual size converted to the number scale (0=XS, 2=M, 3=L); size down only if you want a trim fit in the relaxed tees and sweats, and size up in fitted jersey styles.

The most detailed owner review of a James Perse jacket — the brushed-fleece long jacket — praises the finish work: double seaming on the sleeves and shoulders, a partially lined front, and a warm, stretchy hand that wears more like a cardigan than a structured blazer. Brand-wide, longtime owners say the better pieces hold up well and stay comfortable, with several advising to favor the US-made garments over imported runs. The recurring complaint is value: even satisfied owners describe retail prices as several times what comparable basics cost and routinely advise waiting for sales.

Strengths

Owners consistently praise the soft, comfortable fabrics and genuinely careful construction on the better pieces — the jacket reviewer was impressed by the seaming and interior finishing.

Watch out for

Value at full retail is the constant complaint, and owners report quality varies by production run, with imported pieces and thinner fabrics drawing the most criticism.

Sizing

James Perse uses its own numeric sizing (0-4); owners report it maps predictably once converted — a 5'3" woman who usually wears a 4-6 fit her usual JP 2, and a 6-foot, 190 lb man fit a 3 (large).
