White shirts are the worst to render, they tend to get washed out by the time you finish lighting the rest of the scene. This is made even worse on a white background like Patreon's, but these are the raw renders that I used to make the info cards.
The only exception to that is Zoe. I had to make two renders of her get it working with her hoodie...
The first one with hair,

and a second one without hair.

Then I combined the two using masked layers in gimp for the end result.
