St. John Blazers

Most St. John knit jackets sell for modest money secondhand, but the beaded and runway pieces are a separate, far pricier market -- so a 'St. John' price tells you little until you know which you're looking at. And the vanity sizing is aggressive: a labeled size can fit two sizes larger, so buy on measurements, never the tag.

Buying Secondhand St. John Blazers

St. John boucle knit jackets are undervalued on the secondhand market, but two things trip buyers up: the wide gap between the everyday knit jackets and the collector pieces, and vanity sizing aggressive enough to make the label almost useless. Getting both right is most of the work.

Everyday Knit Jackets vs Collector Pieces

The standard boucle knit jackets sell cheaply, while the beaded, sequined, and runway pieces command far more and behave like their own market. A 'St. John' price tells you little until you identify which kind you're looking at -- the plain knit jacket and the collector piece are very different objects under the same name.

Vanity Sizing Is the Real Pitfall

St. John's sizing runs so generous that a labeled size can fit roughly two sizes larger, so always buy on the chest and shoulder measurements rather than the tag. Check the logo buttons, which are brand-specific and hard to replace if missing, and look for snags in the boucle, which show as visible tracks in the knit.
