How do I make my site similar ?

Hello,

I am needing some help and I hope someone can assist. I am subscribed to the Commerce Basic Plan on Squarespace. This website is used for Events and also having Customizable options (Doing Prints) and I have completed the basic things that needed to be added for a Store. However, I intend to make the store more user friendly. I found another website that has the style which I would like to input in my website.

May I know if there are any code/plugins that I can input into my website so that it will look similar to this ? (Photos for reference uploaded)

Any advice will be great !

Thanks,

YC
