Scripting help for a clothing game!

I’m a pretty new developer and need some help with making a GUI where i can click on a certain clothing item or accessory and it will allow the player to buy it, for example I would click on the rig and a GUI would show up with a square containing each accessory

This is an example of what I would like my GUI to look like, I would also like it to have a “Buy” and “Wear” button, and the squares to all have the same spaced gaps depending on the accessory amount, I am able to make guis but need help with the scripting part of it please! :slight_smile:
