Size Guide
Sizing is personal. Here are the real numbers for each cut, straight from our print partner, so you can pick with confidence.
How to use these charts: they're garment measurements (the underwear itself, relaxed and unstretched), not body measurements. The fabric stretches, so the garment is smaller than the body it fits. The easiest way to choose: take a pair you already love, lay it flat without stretching, measure straight across the waistband (or hips) and double it, then pick the size closest to that number. Allow 1–2 cm (about ½ in) either way.
Men's boxer briefs
Sizes XS–4XL. Waist is measured around the relaxed waistband; length runs from waistband to leg hem.
| Size | Waist (in) | Waist (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| XS | 25.9 | 65.9 | 12.2 | 31 |
| S | 27.6 | 70 | 12.6 | 32 |
| M | 29.1 | 74 | 13 | 33 |
| L | 30.7 | 78 | 13.4 | 34 |
| XL | 32.3 | 82 | 13.8 | 35 |
| 2XL | 33.9 | 86 | 14.2 | 36 |

| 4XL | 37 | 94 | 15.7 | 40 |
Women's lace briefs (EU sizing)
Heads-up: EU sizes. Our lace briefs use EU sizing, which usually runs smaller than US sizing. An EU M is not the same as your favorite US M. Go by the hip measurement below, and if you're between sizes, size up.
EU sizes XS–3XL. Hip is measured around the relaxed hip line; length runs from waistband to crotch.
| EU size | Hip (in) | Hip (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| XS | 23.8 | 60.5 | 8.1 | 20.5 |
| S | 25.2 | 64 | 8.5 | 21.5 |
| M | 26.6 | 67.5 | 9 | 22.8 |
| L | 27.9 | 71 | 9 | 22.8 |
| XL | 29.3 | 74.5 | 10 | 25.5 |
