I see the appeal of Alexa's style, and of course her long, lean limbs and general skinny aesthetic, but her face....? I simply have no idea how she was ever deemed suitable for modelling in the first place. She is not unattractive, but certainly not model-worthy in looks to me at all. The biggest issue is that her eyes are so close-set, and that the rest, whilst not unpleasant, is simply bland and nowhere near striking or interesting enough to save her face from an overall air of horsiness.
Do I get her appeal? Neigh. Don't get it. At. All.
