I love this look on Monica! It's a great Saturday look that can literally take you from morning to evening. Brunch, shopping (as she is doing), drinks & tapas and even a late evening event (with a quick change of accessories).
The older I get and the busier my schedule gets, the more I love looks that I can put together in 3 pieces or less LOL. That's why I ADORE dresses. This is very similar in ease to me.
I also like the option of the scarf. Since I'm new to the whole "strapless" dressing, this allows me to feel a bit more covered, yet still shows the style of the outfit. Plus it's great for chilly restaurants or for the cool evening air.
