I reopened my store that was used to be hosted on Tictail. You can now find it on the following address: salayanara.net/store/ (in French only but shipping is worldwide).
You will also get a 10% discount on all the store with the following code: OPENING
For some backstory, Tictail got merged with Shopify back in April and every store that was hosted there has to close. After searching for a decent alternative, I finally decided to setup my own store from scratch and host it on my personal website. And voilà!
The store might still have some bugs, so feel free to report them 
Cheers!
