This is if you want just the swim shirt💛
This is the "add a shirt" feature.
Maybe youbalready ordered a skirt form us or somewhere else and youd like to match it with a top?. In the custom section, confirm the skirt you'd like to match the shirt to :) 
We will automatically make the sleeves "t-shirt" length unless you request otherwise in the custome section.
The body will be a solid color.
The sleeves and neck line will be the print.
