I like the black one but it might show up dog hairs too much! I like them all - probably the third one if I had to choose.
I like the black one because black is my favourite colour for clothes. I know black shows every dog hair but with me its a case of "love me, love my dog hairs"
I do not wear white [or pale colors] - not because of slobber but because I am a clumsy git and am always ending up with my food either on my crumb catchers or in my lap!
