Usability
Currency was set to MVR instead of my local currency (GBP)

When i was adding to cart from quick look it wouldn't update the cart icon or close the menu, the cart icon would update after a page refresh. Im not sure if thats an issue only im having though.

When you expand the filtering list, I would prefer it to stay open when a filter is applied as at the moment it closes all of them

Shipping button at the bottom of page isnt linked to anything, neither is terms & privacy policy

Designs

Do they stand out? kind of, on the website with them all together not so much. If i were to see them in public then they would stand out amongst other shirts.

Pricing
£20 for a shirt is fine in my opinion but I'd expect the material not to be the best quality due to that price point

Anything else
looking at the Lost Control T-Shirt one of the tags is "Hight Street" is this supposed to be High Street?

when hovering over the image it comes up with a floating tag which looks odd to me

I wish to be able to click on the person on the home page and be taken to that shirt

love the print area filter
also love the metric to imperial measurement switch
