Vintage French Terry Sweatpant - 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.
