About size dimensions (actual size)

Important notes

• Size dimensions are measurements of the final products.
• All size dimensions given are outer measurements of the product laid flat on a flat surface.
• Size dimensions and nude sizes are different measurements.
• The product tag displays nude sizes and not the size measurements.
• The outer dimensions are measured by hand. Therefore, there could be a slight difference (1~2cm) depending on a product.

Measuring

• Outer dimensions of stretch items are measured unstretched.
• Collar is not included in the measurement of collared items.
• For items with frills, gathers, and pleats, the outer dimension is measured with items stretched flat.
• The outer dimensions of down jackets are measured with down pressed flat.
• We recommend measuring items you own to compare specs for figuring out your best fit.
