Another person wrote: "Sorry Lauren Sanchez. Put them away for a day."

Another X user he exclaimed"Lauren Sanchez is wearing a bra."

A fourth person lamented: "Just when I was enjoying the beauty of @FLOTUS45, Lauren Sanchez was wearing only a bra on the walk."

A fifth X user shared: "Lauren Sanchez completed an inappropriate dress today. Indeed, the bra is clearly visible. Today is NOT a night club event. Show some class and dignity."

Although Sanchez was criticized for her bold choice of outfit at Trump's inauguration, there were more positive reviews for her on Sunday night.
