I got the 4P, my usual size in jackets. The waist is unusually nipped and the hips are unusually flared, so it doesn't fit like the usual staid blazer. (2Ps are often too tight in the arms and pull at the bust on me, and this jacket was no exception.) When I got home, I ordered the pants in Petite and regular size (since I don't really want ankle pants), but since I will be in the vicinity of a bricks'n'mortar, I think I will try on other sizes.
I tried on the Halogen knit jacket, and it didn't fit at all, or rather, it fit like the Gibson jacket on me -- too broad at the shoulders and more like a Junior fit.
A bricks'n'mortar can order a jacket for you from other stores to be sent to your home so might be a more rewarding option than checking online.
