How to Choose the Right Suit Size Online?

How to Choose the Right Suit Size Online?

Ordering a suit online should be easy. No crowded stores, no pushy salespeople, no long fittings. Just a clean, simple experience from your screen to your wardrobe.

Still, we get it—finding the right size is the #1 hesitation when shopping online. That’s why at Monsieur Future, we’ve made it as easy as possible to get a perfect fit on your first try, using EU sizing and a smart combination of guidance and technology.

Here’s how to choose your size with confidence.

1. Know Your Size (Body Measurements, Not Garment)

Our suits follow EU sizing, which is your chest circumference in centimetres. Example: if your chest measures 100 cm, you’re a size 50 (100 ÷ 2 = 50).

Here’s what to measure:

Chest: around the widest part of your chest

Waist: at belly button level

Hips: around the fullest part of your seat

Inseam: from crotch to ankle

Height: in centimetres, to help determine length

2. Use the Fit Finder

Don’t feel like measuring? Try our AI-powered Fit Finder on the product page.

Just enter your height, weight, and body shape. In a few seconds, you’ll get a size recommendation for jacket and trousers, along with suggestions for a slim or relaxed fit depending on your preferences.

3. Choose the Fit That Matches Your Style

We offer a Tailored Fit—a clean silhouette with structure, but room to move thanks to the stretch fabric.

Prefer something looser? Size up.

Want a sharper, more fitted look? Stay true to size or size down if you’re on the edge.

4. Quick Tips for Jacket Sizing

Shoulders: The seam should align with your natural shoulder.

Chest: Jacket should close comfortably, no pulling.

Sleeves: Shirt cuff should peek out by ~1.5 cm.

Length: Should cover your seat, not more.

5. Quick Tips for Trouser Sizing

Waist: Match your jeans size. Size 42 jeans = 42 trousers.

Length: Pants come finished.

Bonus: Our Size Guarantee

If your first choice isn’t a perfect fit, exchanges are quick and free. But with the right measurements and our Fit Finder, you’ll likely get it right from the start.
