I've been planning to sew Simplicity 2603 since last year around this time. I'm only a year late. I really wanted my fabric to marinate before I used it! The fabric is some kind of knit of unknown origin from Walmart and probably only cost $1 a yard.
I don't think there is anything I could say about it that hasn't already been said. There are 73 reviews of the pattern on Pattern Review. It's easy and can be styled many ways.
Here's Lynn from You Sew Girl styling in it at the sewing expo. I think we both look great!
