Find Your Fit
Every shirt starts with the right fit. Here's how to find yours.
Five Fits. One Standard.
We offer five distinct fits across our shirt collections — each designed for a different preference and body type. Whether you like it sharp and tailored or relaxed and easy, there's an R.S.P. fit that works for you.

Slim Fit
Sharp and defined.
Our most tailored cut. The Slim Fit is cut 2.0 cm (¾") narrower through the torso than our Modern Fit, offering a clean, close-to-body silhouette without restriction. Designed for those who prefer a sharper look — best suited for slimmer builds or for wearing under a blazer.
Modern Fit
Our most popular cut.
The Modern Fit is our best-selling everyday shirt — tailored enough to look sharp, with enough ease through the body for all-day comfort. It sits neatly without being tight and works equally well tucked or untucked. If you're unsure which fit to choose, start here.
Classic Fit
Timeless and easy.
A slightly relaxed silhouette designed for easy, traditional wear. The Classic Fit offers more room through the chest and body than our Modern Fit while keeping a clean, structured look. A great option for those who prefer a little more space without sacrificing shape.
Regular Fit
Room where it counts.
Our updated Regular Fit provides an additional 3 cm (1¼") of room in the waist for added comfort, while maintaining the same structured silhouette. Designed for those who want a little more breathing room without going fully relaxed — ideal for a comfortable work shirt.
Comfort Fit
Maximum ease.
Our most relaxed fit. The Comfort Fit features extra room in the chest, waist, and hem compared to the Regular Fit, with a slightly shorter back length — designed specifically for wearing untucked. If all-day ease is your priority, this is the one.
How to Measure
Use a soft tape measure and stand naturally. Measure over a light layer or bare skin.
Chest
Measure around the fullest part of your chest, just under your arms. Keep the tape level across your back and don't pull it too tight.
Waist
Measure around your natural waistline — the narrowest part of your torso, usually just above the belly button.
Neck
Wrap the tape around the base of your neck where a collar would sit. Slip two fingers between the tape and your skin for a comfortable fit.
Sleeve Length
Measure from the centre back of your neck, across your shoulder, and down to your wrist bone with your arm slightly bent.

Measurements may vary slightly by style and fabric. If you're between sizes, we recommend sizing up for a relaxed fit or sizing down for a more tailored look.
