It's a hell of a lot more than Mrs. Mountain would ever pay ... but at the high end of 'fashion' for rich people it's peanuts.
Ivanka where’s clothes from her business line all the time that are reasonably priced. $1655 for a dress to wear on 60 minutes is very modest IMO. no reason Melania ever needs to wear anything expensive, but for the white tie inauguration, they’ll expect her to wear potato bag clothing, and of course she’ll look great in it.
