One of the great things about this time of summer is all the sales that happen before the fall season. Right now, the most beautiful dresses are on sale at Le Train Bleu and I love this Cacharel Purple Chemise that's on sale for only $145 (was $290). I love the flirty 20's shape and it's a great dress to wear to a wedding or dinner out.
Here's more gorgeous dresses on sale from this page:
Development Bell Sleeve Dress ($129.00)
Iben Hoj Lace Pleat Dress ($89)
