Shopping help needed

[lindyhop]

I hate to shop. There, I've said it. And I especially hate to shop for something specific because it's guaranteed not to exist.

My son is getting married in a month, a month! I bought a dress but it's sleeveless so I want to find some kind of wrap or jacket or something to wear with it. The dress is a floral print that ranges from a medium rose to a purple that is almost black, all on a dark silver background. I want to find something that matches that silver color in a jacket or shrug or shawl that keeps the whole look appropriate for a dressy occasion.

I know that many of you swanky people can find cool stuff on the internet. I don't have that talent. Or perhaps you could suggest a store. Help!
