Translating my store

Hi there!

My Shopify store is : https://www.teeezy.com

I'm considering having it bilingual (English and French), as I live in Canada. I would use an app for most of my translations (probably Translation Lab, as it's free and seems to do a good job). Unfortunately, most of these apps don't allow to show a different collection for different languages (my t-shirts have different texts and logos for both languages). This would require some special if/then cases for various languages as seen in this document :
