Ordered size Medium for my 27lb corgi and a size small for me (130lb, 5’4” female). Both fit absolutely perfectly; the size guide was accurate and easy to use. Our order shipped within 24hrs and came wrapped beautifully in tissue paper. Mostly I’m impressed with the quality. In the images, I was fearful it would be “cheap” or thin, but the outfits for both of us are super soft and high quality. Hope to order again soon!
