What size would you need? Ive got 3 patterns for xxs clothing. I have 1 for harnesses that could be a harness, have a tutu attached for a tutu dress, or have fabric for a skirt attached to make a dress that states it is for digs 1.5 to 3 pounds, with a chest of 8-10 inches. That same pattern has the nect size up if thats too micro.
Then I have one that has 3 styles of dresses in it that states it is suitable for dogs with a body length of 8-10 inches and chest 15-18 inches.
Then I have another that had a few dresses, a shirt with long sleeves, a nightgown, and a bikini (although you probably wouldn't need a bikini in the winter...lol) that states x small is a neck of 6-8, girth of 8-10, length of 8-10, and approx weight of 2-4 pounds.
I also have patterns for leg warmers and scarves.
And coats too.
Anything particular you have in mind? If you'd like, I could make something for you. Hope that helps.
Good luck on your search!
