Martina Briefs Sizing

The Martina Briefs are made from a soft woven fabric with no stretch in the fabric itself, but with plush 8mm elastic around the waist and legs to ensure comfort and flexibility. They offer the same cut and silhouette as our Ruffle Knickers but feature a smoother, simpler finish without the ruffle detail.

The plush elastic in the Martina Briefs doesn’t stretch as much as the elastic in our Ruffle Knickers, so the waistband is cut slightly wider. They’re designed so you can choose the same size in both styles.

Size Flat Waistband (cm) Fits High-Hip of (cm) Stretches Max
Over Bum, Hips or Waist (cm)
XS 64 89 up to 94
S 72 94 up to 100
M 74 99 up to 105
L 80 104 up to 110
XL 71 109 up to 115
2XL 75 114 up to 120

If you’re in between sizes or prefer a relaxed fit, I recommend sizing up. And of course, if you ever need sizing advice, I’m just a message away.


With care,
