Xsmall Dog

I have a lovely 4lb. teacup Chihuahua, How can I find proper apparel for her? ?

I've tried at Pet Smart and Target with xsmall clothes for her but everything, even if it's marked as XS, is really big on her. I understand those might fit to fluffy small dogs, but her she is not the case. So now with the weather getting cold I'm trying to get her some cozy jammies or so. Can anyone help me with some advice on that matter?

walmart has some xxs clothing , I recently saw these, but you can ask petsmart or target to order xxs for your dog and i am sure they would order for you. you can also order xxs online here are a few links:
