Criticism of Michelle has more to do with her choice of color and style (or lack thereof: think boob belts; plaids, stripes and garish color; ostentatious gownage; and more) than her plump derriere.
It’s not her thickness that bothers me. Thick is muy bueno in my book. My big hang up is her attitude and narcissistic personality, and it extends into the ridiculously expensive garments that she chooses to wear.
