Hi there @arnika!
Don here from Shopify.
Thanks for taking the time to share your query with us here in the Community.
Any theme you download for your own Shopify store from our theme store would be compatible for use with your Shopify store.
How you would get support for your theme would depend on if this is a free Shopify theme or a paid, third-party theme.
You can see on each theme store page who a theme is created and supported by as well as see links to their documentation or support pages like so:
So in your case, the Prestige theme being a paid, third-party theme it would be supported by its developers Maestrooo rather than by us here at Shopify ourselves.
I'd advise you to check out the support offered by a given developer in terms of what they can and cannot provide support for before committing to purchasing a theme.
There's more info here on our help site on how adding, previewing, and purchasing themes would work for your store.
Are you starting out on a new business venture or looking to expand on an existing one?
Let me know if you have any other questions about any aspect of using Shopify at all!
