Any thought on the LV Damier Chelsea bag?

It's a great bag, I love it. It seems to be very useful, easy to wear and low maintenance! I don't own one so I can't answer your question about the straps.
 
I have this bag, and use it for a tote on a number of occasions - for work, etc.
I've used it as an overnight bag (like when the overnight does not require alot).

It is the perfect bag go-to have. If you get it , you will use it !
