Try not to stress about the lack of sales, 3 monoths without a sale is actually not uncommon. Besides, your site is BEAUTIFUL. Great job!
What kind of SEO work have you done so far? If you need some pointers read through THIS. I also can't seem to find you on facebook, instagram, or twitter. Those are great avenues to increase traffic, but you'll have to make sure the accounts made for your business are accessible. Try doing some searches for your products in a Google Chrome 'Incognito' window to see unbiast results of how the world might find you.
Once you have your social media set up do some contests! Instagram is full of great contests asking people to share and tag their favourite product for a chance to win free swag. That should get a few people to skim through your site and that 10% discount you're already offering will be a great hook to buy.
Just try and remember that fashion can be a notoriously difficult market to get into. A way to hold on to a regular client base is to build a community around your brand! Keep up with social media, maybe set up some fashion tutorials on youtube. Have fun and be creative!
First off, your site looks fantastic - well done! One thing I noticed right off the bat is that you could definitely make the navigation menu pop a little more by making it bigger or a different colour. Right now it's a little hard to see - https://snapify.shopifycdn.com/2015-05-21_20-59-53.png
In terms of traffic - I'd look into using Google Adwords with that discount code on your Discounts page as well as maybe some Facebook ads, just to get people browsing! Our Shopify Blog has a ton of resources on how to improve your marketing and make your first sales as well. This would be a great one for you in particular - 50 Ways to Make Your First Sale.
I would suggest to put your phone number on the site. Buyers need to know you're only a quick call away if they have an issue.

I also find that your main images are stretched too large creating them to look cheap and pixelated. I also don't find them that appealing. To me, they look very generic. If I were you I would use photos of your products if you have high quality large images of them. I would use products like the Slub Coffee Tank, The Polka Dot Romper and a jewelry pic or some shoes. As of right now with the main images, it doesnt look like you sell jewelry or shoes. Just clothing, and very generic clothing at that. Which after checking out your apparel, it doesn't look like you do sell generic stuff. The peices you have are actually quite cute!
That's just my initial reaction. And these days, people have no attention span, so you really want to grab them.
