You need to work on your spelling in some listings. Under your About you page, you misspelled Owner and designer. You need to utilize all 5 photos and get some pictures of a model wearing the item. Your descriptions are lacking in detail.
You need to make sure you include measurements of both the item and the necklace lengths. In one of your listings for a choker necklace, you stated it is a standard length....that is not sufficient.
You need to work on SEO. Use 2-3 word tags. Use phrases that you think your customers might use to find your items.
Your items are very cute, but those are some things that I would do to make them even better.
