I fell in love with this bag when I saw it on Angelina Jolie, so I ordered the large size from Celine in the pearl color which they told me was a grey-white with the option of exchanging for white (not yet available) if I did not like the color. The bag I expected to receive has straps around the ends, but the bag I actually received does not. Now Celine tells me that the strappy bag is $500 more (and only available in white) and has not come in yet. Do I keep the bag I have, exchange it for white, or exchange it and add $500 for the strappy bag in white which was the bag I saw on Angelina?
