I was a little nervous to try them on my Brewski at first due to him being in between sizes. However, I am so happy that I went with the XL like the amazing and helpful folks at Pittie Clothing Co suggested. They are soooo cute and fit my Brew perfectly. I've bought quite a few clothing items for my fur baby but nothing has fit as good these pajamas and the quality just by feeling them is top notch. There will definitely be future purchases for more of these!! :)
