At a glance<\/p>\n\n\n\n

Give personal size and fit advice before checkout by adding a personal AI stylist to your Shopify product pages. It asks each shopper her height, usual size and how she likes clothes to fit, then names her size in that one piece. Test it privately first. Shoppers order one right size, so fewer orders come back.<\/p>\n\n\n\n

A shopper is on your product page with her thumb over the size selector. She is 5’3″, usually a 10, and wider at the hip than the waist. The size chart gives her numbers, but it cannot tell her which size of this dress will sit right on her.<\/p>\n\n\n\n

Personal size and fit advice is an answer to “which size, and will it fit me?” given for one shopper and one piece, based on her body, her usual sizes and how she likes clothes to fit. It is the fourth Return factor in the Styling Score, and it cuts the return rate: every order that fits the first time is a sale that stays sold.<\/p>\n\n\n\n

This guide is about the moment a shopper chooses her size. To answer whether a piece suits her style, read how to answer “will this suit me?” on Shopify product pages<\/a>.

A salesperson<\/p>\n\n\n\n

points to the size chart and leaves the shopper to guess between two sizes.<\/p>\n<\/div>\n\n\n\n

\n

A stylist<\/p>\n\n\n\n

asks how she likes clothes to fit, then names her size in this piece and says why.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Why does personal size and fit advice cut returns?<\/h2>\n\n\n\n

Personal size and fit advice cuts returns because size and fit is the top reason clothes bought online come back, and a personal answer replaces the shopper’s guess.<\/p>\n\n\n\n

A size chart gives measurements, not judgement. A shopper between sizes still has to decide alone, so she often orders two sizes and plans to send one back. That habit is called bracketing, and every bracketed order is a return before the parcel even ships.<\/p>\n\n\n\n

Personal advice works on the cause. When the store asks about her body and her fit preference and then names one size with a reason, she has less reason to bracket. Fewer returns means fewer refunds, less return shipping and less stock stuck in transit.<\/p>\n\n\n\n

More than half of the US apparel brands and retailers surveyed named size and fit as the top reason online clothing orders are returned, far ahead of colour and damage.<\/p>\n\n\n\n

19.3%<\/p>\n\n\n\n

Fit help can win sales as well as keep them. In the same Coresight survey, 80% of the retailers that already used a size-recommendation tool said it raised their conversion rate (Coresight Research, 2023).<\/p>\n\n\n\n

What does good personal size and fit advice look like?<\/h2>\n\n\n\n

Good personal size and fit advice is available on every product page, asks the shopper about herself, and answers for that one piece with a size and a reason.<\/p>\n\n\n\n
