Every Koibito piece is handmade to order, which means your order is cut and sewn for you — so a minute with a tape measure now means a perfect fit later. All measurements are listed in inches and centimeters.

Each garment below has two tables. Find your size compares your own body measurements to each size. Garment measurements shows the finished item laid flat — handy if you want to compare against a favorite piece you already own. Because each piece is made by hand, finished measurements can vary by up to 1″ (2.5 cm).

How to measure

Keep the tape measure parallel to the ground for all horizontal measurements.

• Chest — wrap the tape around the fullest part of your chest, under the armpits and over the shoulder blades.
• Underbust — wrap the tape right under your bust, where a bra band sits.
• Waist — measure around the narrowest part of your waist.
• Hips — start on one hip and bring the tape around the fullest part of your hips.

Note: available sizes can vary by print — each product page lists the exact options for that design.
