Hobo purchase?

My medium veneta hobo arrived 2 days ago. My husband said "well, do you love it?" and I truthfully said, "no". I want to love it but just don't. Maybe it's the shade of gray. It's all wrapped up ready to return.

I'm 5'6", 120 lbs, narrow shoulders.

Does the Belly bag have a larger arm hole than the medium hobo?

Maybe I am a better candidate for the pillow. I noticed on the BV website that pillow does not come in black. How could that be?

Now after reading comments, I'm concerned the narrow strap will dig into my shoulder. If I don't overload it with weight, is it comfortable?
In the beginning I thought that everything available was represented on the BV site. But that's not true. Try bergdorff's or Neimans. Black pillows are out there.
