I just read through this entire thread, I guess I missed it before!
 
I think the key for me came when Kewtee said that her English was a bit rusty.  When you say that something "looks funny" people automatically construe that as being that it "looks strange".  But I think what she meant, gathering from the content of her posts, was that it "looks cute" or "looks amusing", as in it puts a smile on her face.  Reading further down, I see that Kewtee is a doggie dresser too!   
  
I decorate everything I love that will allow me to decorate it.  I paint the walls in my craft room, I glue rhinestones onto my cell phone, and I dress up my dogs.  I think it would be strange if I DIDN'T dress them, LOL!  For all the joy and happiness my dogs bring to me, what I do for them is just a drop in the bucket of repayment.   
Some clothes are a necessity, like coats and sweaters in the winter.  I figure hey, why be plain, let's get CUTE coats and sweaters!  And I don't like wearing the same old thing every day, why should they? 
I paint their toenails pink, because pink is my favorite color, and it's fun to see them painted.  They have cute little sterling silver necklaces, because they're just pretty, and I like pretty things.   
I don't have human children.  These dogs are my kids, and I can guarantee you that if I had human children, I'd dress them in the cutest clothes, and do their nails, and buy them jewelry too!
