Grey dress vs cream dress for a wedding (which should I wear)?

I think it might be better to go with the grey one and the accessories. Do you know anyone else going to the wedding who you can talk to about their choice of outfit? I'm guessing that you won't be the only person at the entire wedding to deviate slightly from the theme so it shouldn't be too big of a deal. You can probably return the long cream dress but you might have to pay for return shipping depending on where you ordered it from, check their policy. If you decide to go with the cream dress you could try to find a way to make it more flattering by possibly adding a belt or pinning parts of the dress discreetly. I'm leaning toward the grey, though.
