Customisation of your Shop Front is already possible via the Template Picker in their Dashboard Menu so you can choose from the available new templates the one which better represents your business:

Currently we added 6 new templates which are:

Elegant : elegant-theme.uenishops.com

Modern : modern-theme.uenishops.com

Luxury : luxury-theme.uenishops.com

Organic : organic-theme.uenishops.com

Relax : relax-theme.uenishops.com

Beauty : beauty-theme.uenishops.com

To use any of these templates, all you have to do is go to Templates on the left side menu on your Dashboard and click Apply.

After that you can go to your Shop front and check the changes.
