Web shop redesign

I have a web shop selling women's cloths. I designed it a couple of years ago with shopify. So far, I think it has been "ok" yet in order to really stand out in the fashion world and to take-off regarding sales I need to bring it and its design to a more professional next level.
I got couple of ideas in my head and also did some research of what looks great. I could use a different shopify theme or I'll find an expert who will re-design my web-shop beautifully.
Thank you.
