How can I improve the alignment of Buy Button on Squarespace?

[lisapearlman]

I am using the Buy Button on Squarespace because I invested a lot of time and money into my Squarespace site. I'm having an issue with the alignment of the products' "Add to Cart" buttons, as well as the alignment of the variation drop down menus. It makes everything look sloppy and thrown together. Feel free to check out what I mean here. The password is bokeh

Do you have any links to code that can help make the page look more uniform and organized? Thanks so much.
