Hi Mochi---
1 out of 2 ain't bad, right?
I'm glad you're passing on the shell, as I think you can do a bit better re all the fit issues others raised. I do love the print on you, though! Ann Taylor doesn't have much now but they will often have silk shells in abstract prints.
And the Nordstrom Classiques line tends to have same in moody neutrals, and when sale priced come in lots lower than the Lafayette. I'm also not seeing anything up your alley right now in their online selection.
The tanks are such simple construction you know I can't close without recommending you fabric hunt and hire someone to run one up for you, right?
