Hi Elizabeth,
To me, the neon electric flame is not neon. It's funny when they use those words -- sometimes they really fit, but sometimes not so much. I am still thinking about this red and may go back tomorrow to try it on just to get the possibility out of my head. It is really really beautiful, it has blue/pink undertones, and to me, it's a real lipstick red. Bright but very luscious. It's what I call a "juicy" color, not harsh like I would expect something called "neon" to be.
As for sizing, I am wearing a 4, and it both fits well (shoulders, arms) and is also roomy (by design). I think this is a TTS coat. If you are between, I might be inclined to go down, because of the style -- it does have some built-in extra room, so going up may just be too much. (Also, the arms fit me well, but I do have long arms.) Keep in mind that this coat is sized in numbers (O, 2, 4, 6, etc.), so you'll need to go more specifically than S-M-L.
If I do go tomorrow to try on the red, I will post a picture.
I hope this is helpful.
