Ralph Lauren Purple Label Knitwear & Sweaters: Buyer's FAQ

How can I tell a Ralph Lauren Purple Label sweater is authentic? We authenticate every sweater in-house, and the tells are in the details counterfeiters get wrong. We check the woven purple "Ralph Lauren" label and composition tag, the knit (even gauge, fully-fashioned seams) and the fibre hand — Purple Label uses cashmere and fine wools with a softness mass-market knits can't fake. Because details vary by era, we never rely on a single marker; if a sweater doesn't pass every checkpoint, we don't list it.

What are Ralph Lauren Purple Label knitwear made of? Purple Label knitwear is cashmere and fine wool blends, including the iconic Polo Bear sweaters. Every listing states the exact composition and our condition grade.

How should Ralph Lauren Purple Label knitwear fit? Purple Label follows Italian sizing, and knitwear varies by model from slim crew-necks to relaxed shawl-collars. Check the chest and length measurements we publish per piece rather than the label size alone.

Is a pre-owned sweater or cardigan worth it? Yes. The build lasts for years, so a pre-owned sweater or cardigan at a fraction of retail is sound value, and every pre-owned piece is graded transparently (Unworn with tags, Unworn, Excellent, Very Good). And every piece is authenticated — if one is ever proven inauthentic, we refund it in full — with a 14-day return policy, so you can buy with confidence.

How to Buy Ralph Lauren Purple Label Knitwear & Sweaters

From the knitwear we inspect, the tells are pilling or felting at the underarm and cuffs, the elasticity of the ribbing, and any thinning or pulls in the knit. We grade each of these before a sweater is listed, new or pre-owned.

Layer Purple Label knitwear under a blazer or coat, or wear it alone with tailored trousers.

Fold rather than hang, wash cold or have it professionally cleaned, and store with cedar to protect it. Every sweater at Sanpetuna — new and pre-owned — is authenticated by hand and backed by a 14-day return policy; if a piece is ever proven inauthentic, we refund it in full.
