Who Is Kiko Kostadinov? Brand Background
Launched in 2016 by the London-based Bulgarian designer, Kiko Kostadinov quickly gained cult status for his architectural silhouettes, futuristic tailoring, and innovative textile use. The brand’s collections often fuse:
-
Technical sportswear
-
Unorthodox constructions
-
Deconstructed menswear tropes
-
Sculptural womenswear (with Laura and Deanna Fanning co-designing since 2018)
Kiko is stocked globally via SSENSE, MATCHES, LN-CC, and Dover Street Market, with garments that blur boundaries between art, fashion, and performance.
But while Kiko’s style is radical, his sizing system is not always predictable—especially when navigating Japanese production, European cuts, and conceptual layering.
Does Kiko Kostadinov Run Big or Small?
In general, Kiko Kostadinov runs true to size in most garments, but certain categories tend to run slim or cropped, depending on collection and season.
| Item Type | Sizing Tendency |
|---|---|
| Technical Shirts | Slim Fit |
| Tailored Trousers | True to Size / Slightly Small |
| Outerwear & Coats | Structured, Slightly Boxy |
| Knitwear | Slim Fit / Cropped Length |

1. Technical Shirts & Layering Tops
A staple in Kiko’s menswear collections, these are:
-
Often cut narrow through the chest
-
Designed to be layered under blazers or jackets
-
Made in poplin, crepe or synthetic tech blends
Fit Tip: Size up if you prefer a relaxed silhouette or broader movement across the back and shoulders.

2. Tailored Trousers
Kiko’s trousers are known for:
-
Experimental pleating and darting
-
Tapered or flared shapes
-
Often high-rise or mid-rise waistlines
They usually run true to size at the waist, but leg proportions can be stylised.
Fit Tip: Stick to your usual waist size, but consult Tellar if you’re tall or have muscular thighs—cut can vary sharply by season.

3. Outerwear & Technical Coats
From 3D-pocket parkas to twin-lapel jackets, Kiko outerwear is:
-
Structured but boxy
-
Often true to size, with room for layers
-
Constructed using innovative fabrics (e.g., Japanese nylons, Italian twills)
Fit Tip: Order your regular size unless you’re after a slim tailored look—then consider sizing down.

4. Knitwear
Kiko’s knitwear is highly conceptual—think:
-
Slim through the chest and arms
-
Often shorter in length (especially AW collections)
-
Made from merino, technical wool blends, or layered mesh
Fit Tip: Consider sizing up for extra length or if you prefer a more traditional jumper fit.
5. Footwear – Kiko x ASICS
One of the brand’s most successful collaborations, Kiko’s ASICS sneakers (e.g. GEL-Kiril, GEL-Delva) run:
-
True to size for most wearers
-
Slightly narrow in toe box (in early models)
Fit Tip: Stick with your usual ASICS size—or size up by 0.5 if you have wide feet.
Fit Differences Between Menswear and Womenswear
The womenswear line (designed by the Fanning sisters) tends to:
-
Run slimmer and shorter
-
Include more exaggerated silhouettes (like flared sleeves or cinched waists)
-
Feature asymmetric fastenings and layering elements that affect fit
If shopping womenswear, use Tellar to match your bust, waist, and hip measurements to Kiko’s less conventional cuts.
