Baja Stripe Cashmere Cardigan - Heather Grey/Pearl

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.

Third-party coverage of the brand's knits splits sharply on feel versus longevity: forum owners say the fabric feels great and mostly fits true to size, while store reviewers report items developing holes within weeks and the company declining exchanges. An editorial roundup of owner feedback flags rapid pilling from ordinary friction and knits that stretch permanently out of shape if not dried flat, summing up the complaints as 'Simply too delicate for the price point.' Reviews of the sweaters specifically are scarce; most third-party reporting covers the knitwear range as a whole.

Strengths

Even critical owners concede the knits feel unusually soft and fit well when new, and forum owners report some pieces holding up through repeated washing.

Watch out for

Fabric fragility fails first — reviewers report pilling from basic friction, knits distorting after washing unless dried flat, and holes appearing within weeks at prices well above basics level.

Sizing

Forum owners call the numbered sizing mostly true to size, though some report landing between sizes, and one editorial reviewer suggests sizing up on knits to reduce the surface friction that drives pilling.
