Thanks for the input, ladies! I'm going on vacation with my in-laws (including father and brother-in-law), and I'm looking for something that will provide a little more modesty than I'm usually comfortable with. We're staying on a lake, and with my own family normally I'd dry off by sitting on a towel in my bathing suit after a swim, but I thought it might be nice to slip something on (over my modest one-piece) during that period for this trip.
I found a few other open-weave sweaters that are meant to be cover-ups, so I'm giving one of those a go first. This one was particularly spendy and fragile looking, so I'm hoping to find a better alternative - yet along the same lines. I'll report back!
