Melania Trump steals the show in white Elie Saab midi dress: Pics!

A vision in white! Melania Trump attended a cocktail party amid this week's NATO summit in a breathtaking Elie Saab patterned dress.

FLOTUS wore the sheer dress with a nude underlay, which retails for $7,450, after sporting a navy blue Calvin Klein dress earlier in the day. She completed the fit-and-flare dress from the Lebanese designer with a pair of patent nude stilettos.

Melania and President Trump arrived at the cocktail party with fellow world leaders and their spouses at Cinquantenaire, a park designed in the 19th century. The first lady was spotted greeting French president Emmanuel Macron and his wife Brigitte before a group photo.

The first lady started off her sartorial streak for her Europe trip with a pair of Paris-inspired Christian Louboutin stilettos as she left the White House. Upon arriving in Paris, she switched into a classic Burberry trench coat, followed by a stunning blue Calvin Klein look.

All eyes will be on Melania later this week when she finally meets with Queen Elizabeth. For more on Melania's Europe style, watch the video above.
