Lilly Pulitzer Anyone?

I was looking at the Lana top, the Cassie top and then the sweater I wanted is gone

Roughly 90% of my tops (mostly from Express, The Limited, Gap, etc.) are smalls, so I'm leaning that way. But all those stores have that vanity sizing BS and somehow I can fit into a size 2 in some Express stuff. In REAL women's sizes (like my wedding dress for example), I'm like a 6.

I would go for the small in both. Lilly shirts run similar to J.Crew and Gap.
