It can&#8217;t tell one shopper, with her own measurements and the way she liked last season&#8217;s cut, whether to size up or down on this particular piece. A personal AI stylist can, because it answers one shopper at a time from your own catalogue and the fit details you&#8217;ve already written.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">iWAND is an AI stylist for independent fashion brands on Shopify.

Group products by how they&#8217;re cut, not by SKU, and a 200-product catalogue usually needs somewhere between four and ten charts.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1792000000002\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Can I just use one size chart for my whole store?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>You can, but it guesses wrong for most of your catalogue, because different garment types fit differently at the same labeled size. A single chart is the halfway version of this fix \u2014 better than nothing, but it still leaves shoppers unsure whether the numbers apply to the piece they&#8217;re holding.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1792000000003\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">How much does a product-specific size guide cost on Shopify?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Nothing, if you build it with Shopify&#8217;s own page-reference metafields and your theme&#8217;s Pop-up or Size chart block. A dedicated app adds templates and an AI size recommender for roughly $7 to $27 a month, which can be worth it once you&#8217;d rather not build the charts by hand.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1792000000004\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Does adding a size chart actually reduce returns?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Retailers and researchers consistently find size and fit is the single largest cause of apparel returns, so a chart that matches the real garment removes the guesswork behind a large share of them. It won&#8217;t eliminate returns on its own, which is why fit notes and real-customer fit data are the next two factors in this stage.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1792000000005\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Can AI give each shopper personal fit advice beyond a chart?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>A chart still describes the garment the same way to everyone. A personal AI stylist, such as iWAND, can go further by weighing one shopper&#8217;s own measurements and past fit feedback against your catalogue. It costs 5% of the sales it makes and nothing upfront.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\">Sources<\/h3>\n\n\n\n<ol class=\"wp-block-list iw-sources\">\n<li>Shopify Help Center.
