Finding Your Claudio Lugli Fit
Claudio Lugli shirts are cut with a tailored regular fit — comfortable through the chest and shoulders, shaped for a sharp silhouette. In short: if you're between sizes, broad-shouldered, or prefer a relaxed fit, go one size up. Otherwise, order your usual size and use the garment measurements below to confirm.
9 shirt sizes, Small to 6XL — a more finely graded scale than most brands, so you may take a different label here than elsewhere. Trust the measurements, not the letter.

Measure a Shirt You Already Love
Button it up, lay it flat and smooth it out — then take four measurements and compare them with the garment chart below.
Chest
Measure across the chest just under the armpits, seam to seam. Double it for the full circumference.
Shoulders
Measure straight across the back, from the edge of one shoulder seam to the other.
Sleeve
Measure from the shoulder seam to the end of the cuff.
Length
Measure from the base of the collar down the centre back to the bottom hem.
Our shirts are a tailored regular cut — shaped, never baggy. Small variations of up to ±1cm from stated measurements can occur: these are limited-edition garments, not mass production.

Between Two Sizes? Go One Size Up.
Broad shoulders or heavier set?
Our tailored cut is shaped through the chest and shoulders — if you're borderline on chest with broad shoulders, or heavier set, go one size up.
Prefer a relaxed feel?
The tailored cut sits sharp by design. If you like room to move, one size up gives you the relaxed drape without losing the shape. Taller build? Check body and sleeve lengths too.
Still torn?
Send us your chest measurement and we'll confirm your exact size against the garment charts. Ask us before you order.

Common Fit Questions
Do Claudio Lugli shirts run small?
Our shirts are cut with a tailored regular fit — shaped through the chest and shoulders for a sharp silhouette, not a baggy one. Because of this tailored cut, many customers prefer to go one size up, and we recommend it if you're between sizes, have broad shoulders, or like a more relaxed feel. With 9 sizes from S to 6XL and exact garment measurements in the charts above, the perfect fit is easy to find.
What fit are Claudio Lugli shirts?
A tailored regular fit — shaped through the chest and shoulders for a sharp silhouette rather than a boxy one. Between sizes or broad-shouldered? Go one size up.
Should I measure my body or a shirt?
Measure a button-down shirt you already own and love — it's the most reliable route, because you're comparing garment to garment. Use the body chart only if you can't measure a comparable shirt.
What should I do if I'm between sizes?
Go one size up — that's our standing recommendation for anyone between sizes, broad-shouldered, or wanting a more relaxed feel. Still unsure? Send us your chest measurement and we'll confirm your exact size.
Should I size up for broad shoulders?
Yes — the tailored cut is shaped through the shoulders, so if you're borderline between sizes with broad shoulders, go one size up.
Are Claudio sizes consistent across collections?
Our sizing is measurement-led, and your Claudio size is the best starting point for every collection. Individual products can carry specific fit notes — always check the product page.
