This is J.Crew's Embossed-Cotton Aubrey Halter Dress (item #10681), which is also available in petite (item #11124). It was originally $98, and is marked down online for $78, and was marked down in-store for $49.99. J.Crew describes the dress as such:
The perfect little dress for sun-filled days, on or off the beach. Beautifully textured cotton in a halter silhouette. Fitted bodice with boning and elastic along the top edge for added support. A-line skirt. Straight neckline. Ties start at center front, fasten at back neck. Side zip. Fully lined. Falls below knee; 26" from natural waist. Import. This dress is machine washable, but we suggest dry cleaning to keep it looking newer, longer.I wasn't really interested in this dress (I had seen it around plenty of times), but my PS brought it to me to try on. She originally brought me a size larger than my regular size, in orange, but it was too big, and they only had this yellow color in my size. The yellow color is all right, and so was the orange - a little too bright for me.
I left this dress behind for a few reasons - mainly the color and the bisecting waist. As many of you know, I don't really need any more dresses anyway (although that won't stop me from getting any other cute ones that pop up in the future), and I didn't like this one nearly enough to spend even $38 on it.
