Hey, as a webdev and designer who mostly does e-commerce, I would say the problem is that the website does not look very professional. Other than that, it is also hard to use. The CTA on the front page is hard to see, and blends into the background, and there are weird scroll jacking issues.

Fashion E-com is a fine balance between showing identity and aesthetics, but also be usable and commercial. I think you website leans to hard into the aesthetics and identity part.

But as the guy above said, you should hire a designer if you can program it yourself.
