I like the waterfall cardie but I wouldn't wear it with a jumper, too much knitwear in one place iyswim and yes I know the cardie is jersey but still a cardie with a jumper is a no no imo. A nice fitted jersey top would look nice underneath.
Agree with the general consensus - they're all nice pieces of clothing but the cardigan on top of the jumper will look mumsy, whereas the jumper with a shorter jacket will look much funkier. Unless he's ultra conservative.
LOL. Maybe he knows your MN id and is stalking you and discovered that you weren't going to wear a basque and suspenders and thought "bugger that for a game of soldiers, I'm not bothering to turn up for leggings".
