I have this dress in lavender and black and I adore it.  I call it the "Dress of Requirement"--Harry Potter fans will recognize the reference to the Room of Requirement, a room that transformed into whatever you needed it to be.

This dress is not chiffon, but a lovely lightweight rayon, soft as a summer breeze and so lightweight and breathable that you can just float through the heat looking cool as a cucumber.  It's not particularly sheer, not even in lavender, but because it's so lightweight layering up is not a problem if you think you should.  I wear it as a dress, as a swim coverup, as a nightgown, as a lounge outfit, to the beach, to church, funky with boots or casual with sandals or dressy with heels.  It is The Perfect Dress.

I am an Extra Curvy Girl of Fairly Robust Dimensions but I do have a waist, and the ruching at the waist of this dress celebrates that without clinging anywhere else. Even if you don't have a waist, you'll look like you do in this dress.  It's got that hourglass effect. The looooooong sleeve ties are a little perplexing, but who cares?  The "deep V" neckline is less deep that the description makes it sound, but if that's the effect you're after there are buttons that can be undone.

Get two--or three.  You'll want another one anyway and you won't have to pay the shipping twice.
