First rule of flight club: Never reply to the comments on an Instagram photo in which you brag about your expensive wardrobe as you step out of a government airplane.

Louise Linton, the wife of Treasury Secretary Steven Mnuchin, tagged designers Tom Ford, Hermes, Roland Mouret and Valentino for various pieces of her outfit on Monday as she disembarked from a military plane after a trip to Kentucky with her husband.

Jenni Miller, a 45-year-old mother of three from Portland, commented on the image by saying, “Glad we could pay for your little getaway. #deplorable.”

Rather than let that comment slide, Linton dove into the shallow end of the social media pool and ripped Miller in a comment of her own, calling Miller “adorably out of touch,” adding that she and her husband have contributed more to the country in taxes and self sacrifice than Miller likely has.

“Your kids look very cute. Your life looks cute,” Linton continued. “Sending me passive aggressive Instagram comments isn’t going to make life feel better.”

After screen shots of Linton’s post went viral, she turned her Instagram to private and deleted the post. The New York Times said a Treasury Department official declined to comment on Linton’s post, but that the couple reimbursed the government for the trip. The Times did reach Miller for comment on Tuesday.

“If she hadn’t made her account private, I would have written back with a very snide Marie Antoinette joke,” Miller told the Times. “I think my post was just five or six words, and she had to go on basically a rant about it to make herself look more important and look smarter, better, richer — all those things.”

Mnuchin, a former Goldman Sachs executive, is reportedly worth $300 million. Scottish-born Linton has worked as an actress in film and television.
