Why is Madison asking Allen to make all these changes to his wardrobe and appearance?

I really don't think that Madison will choose to stay with Allen no matter what he does to try and make this work. The wardrobe change and her nixing his comfort in a gold chain to making him feel like he has to change his smile with Smile Direct correction braces? If she can't accept him as he is, what is the point of all this? This is not the woman you want to spend the rest of your life with!
