Can I show a size chart with Shopify Buy Button?

Yes — Tailor Size Guide ships @tailorsizeguide/web (vanilla JS bundle). Drop a script tag + a div on your external site. Reads chart data from your Shopify store via Storefront API. Renders next to the Buy Button.

Where does Buy Button run?

WordPress, Squarespace, Wix, custom HTML pages, blogs, landing pages. Anywhere with a script tag. Tailor Size Guide's web bundle works on the same surfaces.
