I've not other qualifications to judge except that I have an online store myself. I think the site looks real good. And the prices are good. (my personal first point when buying). Pictures are great. But it is really necessary to have a few more (I buy most of my families clothing online and I can tell you a woman really wants a few pictures). It's not just the message you are selling. I learned that you really need to drive traffic. Get people talking and sharing. I found Facebook more active in this way than Instagram. Message a page (in a related field of interest) and ask if they will share a discount code?
Just my 2 cents. Best wishes with it.
BTW, I like your review app. Can I ask which app is it?
