How the Icon cardigan fits
The Icon fit is cut very roomy, with dropped shoulders and long, wide sleeves. Alanui still describes it as true to size, because the volume is the design. Take your usual letter. If you are between sizes, the smaller one keeps the sleeve length tidy without losing the wrap. The Bandana Jacquard Cardigan in Black Multicolour and the Icon Jacquard Cardigan in Canvas and Coffee both follow this fit.
Cardi-bombers, jumpers and tops
Cardi-bombers such as the Icon Jacquard Cardi-Bomber in Charcoal and Russet Red stop at the hip and fit closer through the body. Jumpers like the Sweet Winter Sweater in Onda Multicolour are a regular fit. A few tops are cut differently on purpose: the Rugby Club polos and double-sleeve tops fit oversized, and the cashmere bralettes and the Finest culotte fit slim.
Alanui jeans sizes
| Waist size | 25 | 26 | 27 | 28 | 29 | 30 |
|---|---|---|---|---|---|---|
| Waist (cm) | 63 | 66 | 68 | 71 | 74 | 76 |
| Approx. UK | 4 | 6 | 8 | 10 | 12 | 14 |
The waist measurements come from the brand's jeans table; the UK column is our approximate guide. The Tex-Hawaii Roundtrip Regular Denim Pants in Medium Wash runs from a 25 to a 30 waist.
Giorgio Armani for Alanui sizing
The tailoring from the Giorgio Armani for Alanui capsule uses Italian sizes. An IT 36 is a UK 4, an IT 38 a UK 6, an IT 40 a UK 8 and an IT 42 a UK 10. The Giorgio Armani for Alanui Trouser in Navy and Giorgio Armani for Alanui Waistcoat in Navy are listed at Coveti in UK sizes.
Model heights
Alanui models are 177cm to 180cm tall and usually wear a size M, which gives a feel for length: on a 178cm frame, the Icon cardigan falls to mid-thigh.
