I took a look at the website that you provided and did a search of our Theme Store to find themes with similar visual and user experience elements. Here are some of my recommendations:
Impulse - The logo is in the middle of the page, above the main image in the header. When hovering over the different menu items, a sub-menu item appears just underneath the main menu, to show links for each collection.
Responsive - The logo is also central here and the full-width of this theme allows you to showcase your products and brand more.
Editions - This theme has a minimalist feel, with the ability to add your products on the home page, allowing customers to place items in the cart, or click on the image to view more information about the product.
Kagami - Multiple product images can be shown on the homepage, and when the mouse hovers over the images, there is the option to quickly purchase the item.
You can check out some other grid-style layout themes here. Is there elements in particular you wanted for your store? Feel free to let me know by replying to this thread, and I can take a look at our Theme Store and provide more suggestions!
I’m also curious to see what the community can suggest!
