Does Marni Run Big or Small?
General Fit Summary
Marni typically runs large, with oversized, exaggerated silhouettes that are part of the brand’s DNA. However, because of the variety of cuts and collections, sizing can be inconsistent — especially when buying online without trying pieces on.
Fit Overview:
-
Tops and Knitwear: Intentionally oversized. You may wish to size down for a more traditional fit.
-
Coats and Outerwear: Run very large, especially in unisex and statement silhouettes.
-
Trousers and Skirts: Generally true to size, but the waistband placement (high vs. drop waist) can affect fit.
-
Dresses: Vary by cut — shift styles are oversized, while fitted styles may run true to size or small.
-
Shoes: Often true to size, but can be narrow in leather styles.

Which Marni Pieces Run Big or Small?
1. Oversized Coats and Jackets
Marni outerwear is deliberately roomy and often androgynous. Double-breasted shapes and drop shoulders can overwhelm smaller frames.
✔ Tip: If you prefer a neater fit or are petite, size down one full size.
2. Shirts and Knitwear
Exaggerated collars, wide arms, and boxy bodies are common. If you’re used to form-fitting tops, you may find these very oversized.
✔ Stick to your usual size for the full Marni look, or go down a size for a sleeker silhouette.
3. Trousers and Skirts
Fit depends on the rise and waistband — high-waisted trousers are true to size, but elasticated or drop-waist styles may feel looser.
✔ Use Tellar’s recommendation engine to account for your waist-to-hip ratio for each cut.
4. Shoes and Trainers
Marni shoes, like the cult-favourite Fussbett sandals or retro-style sneakers, generally run true to size, but some leather styles run narrow across the front.
What’s Worth Buying from Marni?
🎨 Coats and Outerwear
From cocoon coats to colour-blocked bombers, Marni’s outerwear is where its sculptural roots shine. These are investment pieces — just be sure to check your shoulder and chest measurement first.
👗 Dresses
Look for bold prints, colour blocking, and architectural draping. Shift and A-line shapes dominate, but fit can vary — Tellar’s sizing engine helps match the dress shape to your body.
👜 Bags and Accessories
The Trunk Bag is iconic, but the newer styles like the Tropicalia Basket and Museo Soft totes are just as popular. No sizing issues here, but be sure your wardrobe supports the brand’s statement styling.
👟 Shoes and Fussbett Sandals
Quirky, comfortable, and always original — Marni footwear is a fashion-forward choice. Fussbett sandals may feel snug at first, but soften over time.
