You can also spiffy it up a little more by making it
Code:
h4.optionName, .wrapperAttribsOptions select { width: 15em; }
input#attrib-4-0 {width:14.3em;}
You can adjust from there to make it more to your liking.

BUT.... You may also want to consider adding some Please Select a ... to your Option Values. Using "Please Select a Size" for the hoodie, "Please Select a Colour" for the hoodie and design, and using a requirement for text in the Custom Name can keep the customer from accidentally ordering something they did not want.

You would add each as an option value to the option name and, when adding to the item in the Attributes Controller, mark each Please Select as "Used for Display Purposes Only" and "Default Attribute to be Marked Selected." Yellow and Gold would now show up in the listing rather than an X.

For the text, you would use the "Attribute Required for Text" selection WITHOUT the yellow or gold. You can add some text asking your customer to enter N/A if they do not want a Custom Name.
