👗 Isabel Marant vs Isabel Marant Étoile: What’s the Difference?

Before we talk sizing, it’s essential to understand that Isabel Marant has two main lines:

• Isabel Marant (Mainline) – High-end, structured, luxury-focused with elevated fabrics.

• Isabel Marant Étoile – More casual, relaxed fits, youthful energy, and slightly more affordable.

Both lines can have varying sizing tendencies, especially since they’re manufactured with French and European sizing standards in mind.

📏 Does Isabel Marant Run Big or Small?

Short answer: Isabel Marant runs slightly small overall – but with a few exceptions.

Key Sizing Takeaways:

• Tops and blouses can run small in the shoulders and arms.

• Dresses and skirts may come up short or fitted through the waist.

• Trousers and jeans tend to be slim through the hips and thighs.

• Jackets and coats are often oversized – especially in the Étoile line.

• Shoes and boots typically run true to size in EU sizing.

📊 Isabel Marant vs UK Sizes: What to Expect

🧥 Isabel Marant Fit by Category

1. Tops & Blouses

Expect delicate, structured fabrics that don’t always offer much give. French sizing often translates to a more narrow shoulder and shorter torso cut. If you’re broad-shouldered or tall, sizing up is advisable.

2. Dresses

Floaty boho shapes may look easygoing, but they often have narrow underarms or shorter hemlines. Wrap and tie designs may appear adjustable but still follow slim proportions.

3. Trousers & Denim

Marant’s jeans and tailored trousers are slim and high-rise, particularly in the mainline. If you’re curvy around the hips or thighs, consider a size up or opt for more relaxed Étoile cuts.

4. Jackets & Outerwear

Oversized fits dominate here – especially in the Étoile line. Expect slouchy shoulders, dropped sleeves, and generous silhouettes. Stick with your true size unless you’re petite or prefer a closer fit.

5. Footwear

Most Isabel Marant boots and shoes run true to size, but half sizes are rare. If you’re between sizes, go up rather than down.

🛍️ What’s Worth Buying from Isabel Marant?

Whether you’re shopping for timeless staples or standout luxury pieces, Isabel Marant is rich with wardrobe investments. Here are the categories that consistently deliver:

1. Western-Inspired Boots

From the iconic Dicker and Luliana boots to pointed knee-highs, Marant’s footwear blends quality leather with unique shapes. These run true to size and are a lasting favourite.

2. Statement Jackets

Her oversized wool coats, military jackets, and padded bombers are perfect for layering and building out a Parisian-inspired wardrobe. Fit is forgiving but designed to be relaxed – embrace the slouch.

3. Printed Blouses

Expect soft silks, romantic ruffles, and intricate prints. While they run narrow in the arms, they elevate any outfit instantly.

4. Dresses

Ruffled minis and sculptural wrap dresses are key to the Marant aesthetic. Keep an eye on length – many are cut short for a leggy silhouette.

5. Knitwear

Chunky jumpers and detailed cardigans strike a perfect balance between boho and elevated. Étoile’s knitwear runs slightly more generously than the mainline.
