Hi everyone! Please help me decide! I am going to exchange my Ursula w/a new Ursula tomorrow at the boutique. However, I'm now torn between two bags! The Rita and Ursula. I can get the Rita Instead if I want to. I love the design of the Ursula, but it's very very heavy, just wondering if Rita (w/o the strap) is as heavy as the Ursula??? Which color? Black or white? TIA!!
