Melania Trump goes red, white, and blue in $2,790 Ralph Lauren gingham dress for the White House's 4th of July picnic

Toto, I don’t think we’re in Slovenia anymore.

Though she was born and raised in Europe, Melania Trump‘s outfit for the annual White House Fourth of July picnic was as American as apple pie — and, given all that blue-and-white gingham, seemingly inspired by Dorothy in The Wizard of Oz.

The first lady, who joined President Trump in hosting military families for fireworks and food, wore a floor-length dress by a designer long associated with Americana: Ralph Lauren. Mind you, the Rivera gingham evening dress will set shoppers back considerably more than the standard Old Navy flag-print T-shirt; it costs $2,790.

In a move that might make some Revolutionary War historians raise an eyebrow, FLOTUS paired her all-American dress with a red leather bow-tie belt by Alexander McQueen — a label based in Britain. Originally priced at $921, it’s currently on sale for $552.

Last but not least, Trump turned to French footwear designer Christian Louboutin for her red leather flats.

She later tweeted a message sharing images from the White House celebration, which showed her twinning with President Trump, who wore a red tie and dark navy suit for the occasion.
