I absolutely adore Lilly but unfortunately I think it can look a little too overwhelming... especially if you're in a group of sorority girls also wearing bright floral Lilly dresses
I did buy a lovely white lace dress from Lilly for initiation and have several other purchases; I noticed they do tend to run a little small in the bust area, so I have typically sized up one size for that reason and hemmed/taken in the sides accordingly.
As for the sorority collection: not a fan of the totes! Simply because I like the more basic look of the Vineyard Vines totes, but I really love the prints and I'm considering getting a scarf or bracelet, which I think are a little more subtle. Sometimes I think 'Lilly overload' can be a little obnoxious!
