Aw she is so precious...I miss when Sophie was that tiny.
I get what you mean about not wanting to spend a lot of money on something she will grow out of quickly...I just love the coats so I recommend them to anyone lol
Seriously though...I loved using socks on Sophie. They look adorable and you can typically get them pretty cheap...so you aren't wasting money. I think thye have been mentioned on this site before, but here is a youtube video about it:
We have never used the hat part of it because Sophie hates anything on her head.
I am from Canada but from what I hear, Walmart and Target can have some pretty cheap some dog clothes as well. Walmart here sucks for dog clothes....the extra smalls are way too big.
But Petsmart and Petco likely have some decent priced/sized shirts for her.
