Where did you get the dress??
I made it It is the kind that would be classed as formal - some wouldn't. I guess it depends on the fabric. Because it's satin, it's definitely an evening dress. Although I have another cheap satin one that is easily dressed down to day time, and up to evening.

This is the dress I'm talking about. I'm size 12-14, check it out and if you think you'd fit it, happy to lend. I certainly won't get to wear it and would love to see someone feel fabulous in it.

ETA: I'm the one on the left. If you couldn't tell.
