Understanding Japanese Apparel Sizes

Divergence in Sizing Systems

Japanese apparel sizes deviate from the commonly used systems in other western countries, such as the United States or European sizes. While the latter typically rely on numerical or alphabetical sizing, Japan employs a unique system that relies on centimeter (cm) measurements.

Key Measurements and Size Conversion

To determine your Japanese apparel size, it is imperative to take precise body measurements. Here are the key measurements you should consider:

Bust/Chest size:

Measure the fullest part of your chest.

Waist size:

Measure the narrowest part of your waist. Hips: Measure the widest part of your hips. Once you have obtained these measurements, you can utilize our Japanese apparel size conversion chart to find the corresponding size. Our chart encompasses sizes for both women and men and general guidelines for children’s clothing.

Tops and Dresses In Japan, women’s tops and dresses are commonly classified into three size groups: Small (S), Size Medium (M), and Large (L). However, it is crucial to note that these size categories may vary among different brands and designers. It is essential to refer to the specific measurements in the product description or size chart to select the appropriate size that complements your unique body shape.

Bottoms Japanese sizing for women’s bottoms, including skirts, pants, and jeans, follows a distinctive approach. Rather than relying solely on waist measurements, Japanese women sizing considers both waist and hip measurements. This ensures the correct size, a more customized fit, guaranteeing that the garment sits comfortably on your waist and hips.
