That first dress is really cute. It's the first Lilly dress that hasn't made me want to claw out my eyes
It reminds me of Monet. Not garish in the least.
ETA: the lace black for pref. No bolero, that would ruin the effect of the dress. If you don't like how your back looks, pick another dress, but a lot of girls have vertebrae showing. See honeychile's comments.
