All of the comfort of a t-shirt, but in a dress!
The top is a small comfort colors tee! The dress is constructed of an embroidered yellow tee on the top (embroidered with a Splendid Threads Co. design) with a sturdy cotton skirt. The dress is made to be worn and washed and worn again. The tee garment dyed, meaning the fabric has a worn-in, well-loved, perfectly comfy look to it.
I would base your size on what size tee you would normally wear! I typically wear an XL-3XL in comfort colors depending on the fit I want, and in these dresses, I prefer an XL-2XL. I am wearing an XL in the reference photo!
