N.Peal Size Guide: How Women’s Cashmere Fits

N.Peal sizes women's cashmere in letters from XS to XL, and each letter covers a span of UK sizes: XS is a UK 6, S a UK 8 to 10, M a UK 10 to 12, L a UK 12 to 14 and XL a UK 14 to 16. Take your usual letter in jumpers and cardigans, then check the half chest measurement below against a jumper you already own. Every piece in the N.Peal edit at Coveti lists only the sizes the brand makes.

N.Peal letter sizes in UK, US and EU

Classic jumpers, cardigans and tops (cm)

These are garment measurements, not body measurements. Half chest is measured flat from armpit to armpit, so double it to get the full chest of the knit.

Superfine jumpers, cardigans and tops (cm)

The superfine pieces, knitted from cashmere and silk, are cut closer through the chest. N.Peal notes that the superfine fit is naturally slimmer and suggests sizing up if you prefer a looser drape.

Pieces cut this way include the Margot Superfine Cashmere Roll Neck Jumper in Black and the Darcie Superfine Cashmere Cropped Cardigan in Black.

Coats, jackets and capes

N.Peal woven outerwear follows one UK size per letter: XS is a UK 8, S a UK 10, M a UK 12 and L a UK 14. The Suzy Tailored Jacket in Dark Navy Blue has a half chest of 46 cm in XS rising to 53.5 cm in L. Capes and some cardigans come in S-M and M-L, which Coveti lists as S, M and L. The Ayla Fur Trim Cashmere Cape in Pebble Grey is cut generously to sit over knitwear.

How N.Peal fits

• Classic knits are true to size with a little ease. Take your usual letter.
• Superfine knits are closer to the body. Go up a letter for a looser drape.
• Chunky and relaxed styles, such as the Emmie Relaxed Cable Roll Neck Cashmere Jumper in Arctic Grey Melange, are meant to look generous. N.Peal suggests a size down on some of these for a neater fit, and each product page carries the brand's own note.
• Trousers and lounge sets have elasticated waists with a drawcord, so the letter you take in jumpers usually works.

N.Peal also notes that a finished garment can vary by 1 to 2 percent from its size table, which is normal for a natural fibre.

Frequently asked questions

Does N.Peal run small?

No. Classic N.Peal knitwear is true to size. The superfine range is cut slimmer, so size up there if you want more room.

What size is S in N.Peal?

An N.Peal S is a UK 8 to 10, a US 4 to 6 and an EU 36 to 38.

Should I size up in cashmere?

Only if you want an oversized look. Cashmere relaxes a little with wear, so your usual size is the safer choice in a classic knit.

Does cashmere shrink?

Cashmere can felt and shrink in hot water and a tumble dryer. Hand wash it cool and dry it flat. See our guide on how to wash cashmere.

Does Coveti list every N.Peal size?

Coveti lists only the sizes N.Peal makes for each style, from XS to XL, and One Size for capes and wraps.
