Some advice. Too much text. You’re overselling the shirts. Let the designs speak for themselves. When you started describing the tag less tees and how great they’d be at a group function, i thought you were selling blanks on which any design - a company name, a baseball team’s name, etc. - could be screen printed instead of your shirts.
i think selling unisex shirts, instead of dividing them between male and female, is more in tune with streetwear. Women in streetwear love rocking male tees.
I would get rid of the Shopify branding at the bottom. Makes your site look more professional. If you’re on the basic plan, you can edit the footer and remove it.
Also, with regards to the footer, the social media links are hyperlinked to your main page. You’ll want to update that.
Good luck.
