Story & heritage

St. John was founded in 1962 by Robert and Marie Gray after Marie St. John’s straight knit skirts and matching tops drew early retailer orders. The house became known for women’s knitwear: classic wool-and-rayon yarn knits, tailored suits and dresses, Chanel-inspired jackets, primary color confidence, and a knit-in hem associated with its dense double-knit fabric.

Erin Jacket In Santa Roma Knit sits inside the current official St. John assortment as a concrete expression of that house code. The official description grounds it in Santa Roma knit: Tailored to perfection in our signature Santa Roma knit, the Erin Jacket offers the ideal balance of sharp lines and comfortable stretch. Its clean silhouette with subtle detailing redefines the idea of a classic jacket—versatile enough to be dressed up or down with ease. Layer it over dresses, tops, or trousers for a look that’s always impeccably refined.

Materials & craft

The construction language is deliberately controlled: Santa Roma knit, a clean silhouette, and the kind of surface polish St. John uses for pieces that move between workwear, evening, and travel wardrobes. For this product, the official page emphasizes fit, stretch, layering potential, trim, or hardware rather than novelty.

How to choose & style

Choose this as part of a compact St. John capsule: one sharp jacket or dress, one foundation knit, and one clean black shoe. The black versions are the most adaptable; the colored or seasonal variants work best when the rest of the look stays quiet and tailored.
