Just to pile on; it's common for people to comment on what people are wearing when the person in question is famous (as Michelle Obama was during her husband's stint in the White House), but when its the person themselves that are tagging the designers they're wearing, it's really rather tacky, especially when the person in question is married to someone in a government position and was pictured getting off of a plane the American taxpayers pay for, not a private plane (which, I might add, Mnuchin could absolutely afford to do). Michelle Obama was never that crass, to my recollection. Louise Linton, on the other hand, was extremely tacky both in her Instagram post and her response to the person who called her out on her tackiness. It probably didn't warrant the amount of attention it got, but to be fair, if Ms. Linton had not responded, it probably would have died a swift death and be buried in the morass of the internet. She responded, however, and her response was both crass and outright rude. She may have deleted the post, but someone had already taken a screenshot, so she will likely never live it down, despite apologies. For reference, here is the (now deleted) post including both the comment calling her out and her response, although it appears to be slightly cut off. Might provide better context to the blowup for you.
