do you think i should buy this bag?

That's a lovely looking bag. Could easily be worn with many outfits since it has such a beautiful, neutral color.

And $600 looks like a great price, assuming that it's in good condition and not too small. What are the dimensions?
 
It's a very pretty color & a great price,I would go for it.
Does the strap have some kind of knot at the top though,that seems like it may be uncomfortable. Still a great bag & I love the gold charm on the zipper pull.
