This gorgeous Calvin Klein Collection (the most expensive line) is perfect for any time -- day or evening!  Kim K wore a very similar dress and looked fabulous.  Beautiful construction due to asymmetric bands and draping detail, including raglan sleeves and bubble hem!  Yet, incredibly easy to wear -- just slip on!  Wear it on its own or with a belt.  Great for spring and summer, but will also work in colder months with tights and booties.  Retailed for $1.9K.  The dress is exactly the same as in stock pictures of Net A Porter (first 5 pics).
