Feel the Material — It Should Speak for Itself.
Luxury knitwear uses luxurious fibres. Cashmere feels soft, smooth, and light. Merino wool should be fine and flexible, never scratchy. Alpaca and mohair feel warm, fluffy, and slightly silky. If the jumper feels synthetic, plasticky, unusually coarse, or unusually flimsy, it’s unlikely to be genuine.
We are proud to offer a lot of real fibre in our pre-owned designer or mid-tier knitwear, from wool to the cashmere. Cashmere and the wool yarn are safe options, naturally coming from the animals who shred the winter coat or need to have a nice shave. We do not run alpaca goods.
Inspect the Stitching and Finishing
Authentic designer knitwear features meticulous craftsmanship. Stitching should be even, seams secure, ribbing clean, and hems neatly finished. Loose threads, crooked seams, and sloppy knitting are strong signs of a counterfeit or low-quality imitation.
Pay attention to the shoulder seams, cuffs, and neckline — these areas often reveal whether a piece was made with care.
Check Logos and Brand Signatures
If the jumper includes a logo, monogram, or iconic pattern, examine it closely. Designer brands have strict standards regarding pattern alignment, colour accuracy, and logo placement. Counterfeits often make small mistakes in spacing, symmetry, or scale.
There is not a big risk with smaller, independent brands that are genuine and so no worthy of massive copyright. They also rarely mix cashmere with loose rabbit hair to make it into genuine yarn. For brands like Gucci or Dior, the monogram patterns should be sharp, evenly aligned, and consistent. Think also about the original price tag. If so good to be true, it is highly possibly not.
Consider the Overall Feel of the Piece
Authentic designer clothing has a certain presence — weight, texture, drape, and proportions that reflect expert design. When something feels “cheap” or looks disproportionate, trust your instincts. The real luxury and the designer or a good mid tier brand have certain standards, the ensured quality and the look that is understated. If you love the design regardless the noisy or known logo, go for it. Less known brands have often higher quality of the knitwear material used to make the garment. The real stealth wealth, the designer piece is quiet, calm, like a real love, no drama, it is so high quality that it warms and protects you in any weather regardless the storms. You don’t worry about the hole the next week, pillage or thinness of the sweater to keep you cosy. You feel and see often it is good investment and it will last.
