Link direct to a variant and not default item

Hi there.

For example, if I sell:

A white t-shirt in a category, in sizes Small, Medium, Large.

If for example I wanted to link to the Large variant from the homepage, how can I do that please?

I.e. I don’t want to just land on the product page for the white tshirt, but link directly to the item which is set up as a Large variant.

Thank you!
