Hey there, Sandra.
Bo here from Shopify Support!
Congratulations on starting up your business venture with us, super exciting times. You have gotten off to a really good start, I love the images you are using and the color scheme is wonderful. Black and white are perfect for the industry you are in as it is minimalistic and chic.
Taking a look at your store it does look like there is some work to do. Prior to your launch, you will want to make sure that there are no vacant spaces where images should be. You can read up on all the dos and don'ts of launching your site in this guide.
I'd recommend taking a look at our Shopify webinars for sure. These short tutorials take you through all the basics of creating a store such as adding products, variants, collections, theme changes and pointing a domain to your store. You should be able to sign up here http://bit.ly/2SVZC6w if you would like. We also have a free business course with our Shopify Academy that I would really encourage you to look at if you get a chance: http://bit.ly/2Qt6Ay6.
I would recommend getting back to us when you have had done some more work on your site and are ready to launch. By the looks of thing, you still need to add products and sort out your collections.
SEO can play a huge part in bringing in sales and potential customers. The key to SEO is understanding what your customers will be looking for and ensuring your site is set up to best manage the products and content they are seeking. They say 80% of SEO is content.
