Manbag for both casual and bussiness

Hello, I want to buy bussiness and casual leather man bag for carrying stuff and notebook.

I like this bag but I think it looks quite femine because of top holders but I like a little bit idea, that I have this option too.

This is also nice, but I don t know. I am also worried that hunter dark (dark brown) won 't be as good with black shoes and black suit.

and this is bigger http://ift.tt/1Jl5O0k...

So if meseenger, should I take smaller or bigger one? Just from esthetical point of view. My laptop is 13 so both are ok in size.

Thank you
