Gap tie-waist button-front dress ($23)

From Gap's European Collection, the tie-waist button-front dress is available in navy and stucco and is on sale. It's effortless with small details that make is special, like slightly puffed sleeves and banded cuffs. I can imagine playing with toy boats in the Jardin du Luxembourg wearing this dress. Also, you can now order from any Gap, Inc. store (Gap, Old Navy, Banana and PiperLime) and pay only one shipping charge, though PiperLime's shipping is always free so that doesn't really count. Niiice.
