From what I could discern, she was wearing the mini version [left photo below] and it hit her around mid-thigh. Her dress was made of canvas-like material (later learned it was hemp), so the floral print looked like it was painted on. I thought that was so cool and unique. Alas, I knew even if I somehow stumbled across this dress again, it would be much too short on me. My hunch proved to be true when SIL found the mini version when we were in Rome. She's ~5'2" and the dress was borderline indecently short on her. Sigh. The upside was that we now had a brand to go with the dress.

A quick google search on RED Valentino returned a longer dress in the same floral print (!) Unfortunately the longer dress was made of cotton instead of hemp, so the print didn't look painted on. It's still pretty in person, just not as cool looking. The cotton fabric also made a slight swish-ing sound which may bother some.
I first tried on the dress in US 0/IT 38 and found it to be super unflattering. It emphasized my bony torso, so I looked like a long rectangle on top, then all of a sudden, the bottom skirt portion poofed out in an unproportionate way. US 2/IT 40 was looser on me everywhere, so the skirt poofiness didn't look as jarring. SIL (who is shorter and curvier than I am) also tried on both sizes but had the opposite results. The smaller size flattered her curves while the larger size made her look stocky due to its boxiness. I wish we had taken comparison photos because I don't think my descriptions are clear enough at highlighting the differences.
When I wore the dress out for the first time, I couldn't help but check myself out whenever I passed by a mirror, lol. So vain, right?! I kept glancing at the pretty print, and think I fall a little more in love with it each time. I'll probably have the bust area taken in by a tailor some time down the road; it's only noticeably baggy when I lean forward.
The same floral print is also available in a skirt ($198 at BG / $223 at NM / $297 at Saks / $297 at Valentino store) and shorts ($210 at Valentino store) versions.
