Snipcart add to cart different sizes

Hey all, I’m trying to build a little webshop with snipcart. Some articles like t-shirts of course have different size. How can i establish that? Did anybody do that already? Help is much appreciated.

Not sure about snipcart, but there is an addon for gravcart which is itself, if I understand correctly, based on snipcart, written by flaviocopes:

found a solution with “custom fields” in the snip cart reference. Thanks for your help

How did you accomplish this in the frontmatter?

Sorry for the late reply. I ended using paypal buttons. So no real solution with snipcart… sorry
