I need a solution for my Wordpress Dropshipping store

Hi there,
I’m after a solution that will allow custom product options/fields (this is not hard I know), so if the buyer chooses a quantity of three, my site will seek three sets of unique product options. For example, if the buyer chooses a shirt with a qty=3, the buyer can choose three different sizes. If the quantity is 15, then they enter 15 different sizes.

Is this possible for free without buying the mix and match woocommerce addon ??

Any Answer ?

what about oberlo or tools like that

just a suggestion from a half asleep marketer, roast me if silly

Why not limit quantity to 1 so then user will just have to add 15 t-shirts into their basket one at a time?

Do you use woocommerce? If you use woocommerce you can just make variable products and set as many product options as you want.
