Ivanka Trump wore a very distinctive white hat by Irish milliner to the stars Philip Treacy for her visit to Westminster Abbey. 

During the first day of Donald Trump's state visit to the UK, his daughter Ivanka Trump topped her all white ensemble with a distinctive hat by famous Irish hat designer Philip Treacy. 

Ivanka wore a suit skirt ensemble by Alessandra Rich, a designer favored by the Dutchess of Cambridge Kate Middleton and her sister Pippa Middleton. Visiting Westminster Abbey after the President and First Lady lay a wreath at the Grave of the Unknown Warrior, Ivanka added the Philip Treacy fascinator to adhere with proper etiquette.

She shared a photo of herself and husband Jared Kushner in Westminster on social media.

Treacy is known for his trendy, sometimes gravity-defying designs. The fascinator seemed to perch on Ivanka's forehead and featured a large bow that dipped over her right eye. 

Born in Galway in 1967, Treacy was one of eight children, started sewing at age six. He moved to London as a student and became the protégé of famed fashion editor Isabella Blow.

The go-to haute couture milliner for the royals and stars like Lady Gaga, Madonna, and Sarah Jessica Parker, Treacy drew widespread attention for a hat he designed for Princess Beatrice for the 2011 Royal Wedding, which drew some colorful comparisons. He also shared photos of Ivanka wearing his hat to Instagram. 

The president will spend two more days on his state visit in the UK before departing for Ireland on June 5, where he plans to spend two days at the Trump International Golf Club in Doonbeg, Co. Clare. 

This will be Trump's first visit to Ireland since becoming president. It is not known yet if Ivanka will also be going to the Emerald Isle with him.
