Hi Mary,
I LOVE your shop!! Honestly it looks amazing. The colors, the models, the photos, you're killing it. Kensington closet is my second shop, in the process of setting up and I aspire to look as good as yours!
For the first shop I run a lot of sales. End of the year sale for things that you don't feel are moving well, Holiday sales, Tax return sales, etc. I generally do 20% and I at least sell a few things. I am constantly running a 10% off coupon for items that people have left in their carts. Sometimes people just need that extra nudge!
Are you active on social media? Pinterest for your own items, promote on Facebook and instagram! With your already amazing photos I think spending a few dollars on ads for your shop would be well worth it.
I am also a big believer in team games. Fave-A-Thon or view-a-thons get you more traffic to your shop which hopefully results in more traffic!
Best of luck!
