Take over building my website

I’ve been working on creating a blog and have switched from WordPress.com to WordPress.org to host my own site, BUT, I am struggling to make it look good. I need help. My website is https://sincerelydjm.com using the Fascinate theme, but my site looks nothing like it.

The blog is a Lifestyle/Fashion blog so I’d look it to look up-to-date and sleek.
