Thought Alison looked lovely. But please enough of this 'big girls can't dance in heels' nonsense! They can and do. What happens though is big girls who are less active than others often don't have the core muscle strength to support themelves on high heels for anything other than walking. But there are lots of very big women who are active and have very good core muscle strength and can dance fine in very high heels.
Think about it, if you move about with a body that size your muscle groups strengthen pretty damn fast, as it needs to support itself. I've seen some big women with epic muscles doing all kinds of movement, it's just about how active you are. If she wore heels just a few hours a day in training, her muscles would catch up, as of right now she may feel she can't dance in them just cause it aches. She just needs to build up stamina. I hate to compare her to Lisa just cause they are both big, but I think Lisa was physically much fitter than Alison.
As for her dress, I thought it was nice, but I feel she would benefit from support for her boobs, right now they sadly just seem to be strapping them down which makes her look like she has no waist... and yes, she does have a waist.
