There's nothing wrong with the dress in itself, though I agree with pp that it does look a bit summery (even a but spring/summery). If you are planning to get it then I might look at other options, but if you already have it then I definitely don't think it's the worst thing you can wear - it definitely has a wedding vibe and would look nice with a pashmina/shawl or even a casual blazer if you feel more comfortable in that.
