Squarespace is a top favorite for creatives everywhere even if it doesn't specifically address them as a generic website builder. It does have a very modern feel and one of the most intuitive editors out there. Everything looks so simple and within reach, you can tell that a lot of thought went into each tiny detail.
Pricing starts at $12/month for a basic website and $18 will also get you the Business plan which allows you to also sell your art, but you will be charged a 3% fee for each transaction.
If you want the full online store experience you will have to subscribe to a Commerce plan, starting at $26/month, which will also get you a zero transaction fee, on top of inventory tracking, tax features, coupons and all other kinds of e-commerce good stuff.
There's a 14 days free trial and it's definitely worth a test run.
