Hi:
When Tucker was smaller, and didn't have 50 million outfits, I got him a chest that says "little one" on it and stored his clothes in it. I'd gladly sell it to you.
I also use these wonderful boxes that have pictures of various puppys on it (yorkies included). There are large ones that say "toys" on the top and then smaller ones that say "training" or "grooming," but your could use them for clothes if you wanted. These are fantastic! I also have a few extra ones like this I could be convinced to part with
I also took pictures of some baskets I use, to give you some more ideas. Tucker has his own room, all pink! So I have a lot of room for storage. I even have an entire entertainment center devoted to his things.
I hope these pictures give you some good ideas.
