BOSS Fit & Sizing Guide
BOSS is the flagship line of Hugo Boss: refined, modern menswear with a sharp Italian-influenced cut. This guide covers how BOSS fits, its fit types, a chest-measurement chart, and how BOSS differs from HUGO.
The short answer
Most BOSS polos and t-shirts fit true to size. Order your usual size and size down only if you want a closer look. Check whether the style is a Regular, Slim or Tailored fit, because that is what changes the shape.
The fit
Three fits, each clearly labelled on the product. Regular Fit is the classic, comfortable cut; Slim Fit sits closer to the body; and Tailored Fit is the sharpest and most fitted of the three. Most polos and t-shirts fit true to size, so order your usual size and size down only if you want a closer look — the fit type shown on the product tells you which shape you are buying before you commit to a size.

Size chart
Approximate chest measurements. Measure around the fullest part of your chest and match the result to the row below. Fit varies between regular, slim and tailored styles, so always check the size guide on the product page for the exact garment before you order.
| Size | UK | Chest (in) | Chest (cm) |
|---|---|---|---|
| S | 36 | 37–38" | 95 |
| M | 38 | 38–39" | 98 |
| L | 40 | 40" | 102 |
| XL | 42 | 42" | 106 |
| 2XL | 44 | 43" | 110 |
| 3XL | 46 | 45" | 114 |
BOSS or HUGO
BOSS is the refined, modern-classic line. Both labels are part of Hugo Boss: BOSS covers the tailoring, polos and smart-casual staples, while HUGO is the younger, more fashion-led label. At Spiral Seven we stock the BOSS line, so everything in the chart above refers to it. Shop all BOSS
How to measure
Around the fullest part of your chest. Wrap a tape measure under the arms and across the shoulder blades, keeping it level and snug rather than tight, then match the result to the chart above. Bear in mind that the same measurement can sit differently depending on whether the style is a Regular, Slim or Tailored fit.
