Tried on some of the stuff at my local Target:

The leggings are FABULOUS, in my opinion -- super soft and stretchy and not unflattering, surprisingly. They're also nice and long, despite what the website model shows (I'm 5'6" and I can pull them nicely underneath my foot). I'm wearing size S.
The fun thing with the one shouldered swimsuit is that worn with the leggings it looks like a crazy jumpsuit. Unfortunately, the butt of the swimsuit is very small and kind of "squishes in" *ahem*. Not very comfortable.
The harness bikini top is also great, which I have covered up slightly with my own vest in the middle pic. Fits my small boobs very well and is modest yet interesting.
The denim jacket is okay, though the material is a bit too stiff for my liking and the fit of the sleeves is awkward. And the dress does indeed run very small, I tried on the only one left in the store (size L) and it wasn't even that loose. (I usually wear XS or S).
I didn't get anything in the end, though, 'cuz I thought everything was still too expensive. I'm banking that no one will buy the leggings because they're too "crazy" and will thus go on sale quickly.
