I love full coats and topknots on boy Yorkies...I'm just not patient enough for my own sweet boy to pull off that look.
Agreed about the boy clothes. They are harder to find than girl clothes, yet somehow Levi has ended up with tons of clothes...mostly just T-shirts and sweaters. Even local doggie boutiques have slim choices for boys. I've found some nice stuff online. I'll occasionally find cute things at Ross, Target, or TJ Maxx. He generally goes naked in the summer, but wears clothes for warmth in the winter.
Also, Hobby Lobby sells plain-colored dog shirts (mine has black, white, red, blue, pink) that you can embellish with iron-ons or whatever...which we have done for special events and holidays.
