Frequently Asked Questions

How else can I determine my size besides height and weight?

"If the shoulder line fits perfectly, the weight of the fabric will allow it to drape naturally, creating the most beautiful body line. If you are unsure, please use 'shoulder width' as your primary guide."

What if I am between two sizes?

"We recommend the smaller size for a sleek, stylish look, and the larger size for a relaxed, comfortable fit. You can choose based on your preferred fit."

I'm worried if the size will match perfectly.

"Yes, even the lining and threads are stretchy, so the garment will stretch to contour your body, creating a flattering effect. As you wear it, the fabric will warm up and conform to your shape for lasting comfort."

I am tall and slender...

"Please consider whether you prioritize the width (fit) by choosing a smaller size, or the length by choosing a larger size, depending on the item's design and your preference."
