Kiwi Sizing FAQs

Product sizing is often an overlooked part of an online clothing business. Shopping online has more friction because buyers don’t always know if the garment will fit. This is why 20-40% of returns are due to fit issues.

It is important to have an accurate size chart information on every product page with a clear how-to-measure guide.
