JEANS SIZE GUIDE
Vintage sizes differ from modern sizes, but at BOAS we remeasure all jeans to guarantee perfect fit, regardless of what’s on the tag. So you can take your modern size and buy the size you see on BOAS.
All measurements must be taken directly on the body. If your measurements indicate different sizes, it is your hip/seat size that determines. If your measurements are between sizes, choose the smaller size for a fitted look, or the larger size for a looser look.
HOW TO MEASURE YOURSELF
WAIST
Use a measuring tape and measure the narrowest point of your waist. Don't pull too tight.
SEAT
Measure around the fullest part of your hips. Make sure you keep the measuring tape as horizontal as possible.
THIGH
Measure around the fullest part of your thighs.
INSEAM
Measure straight down the inside of your leg, from your crotch to your ankle.
WAIST MEASUREMENTS
Measure your waist and buy the BOAS waist size. If you are between sizes, buy the larger size. BOAS remeasures all jeans to guarantee a perfect fit. You get free returns if it doesn’t fit.
