(CNN) US Rep.-elect Rashida Tlaib will be sworn into office next month while wearing a traditional Palestinian gown.

The Michigan Democrat announced on social media Friday that she intends to wear a thobe to the ceremony.

"Sneak peek: This is what I am wearing when I am sworn into Congress," she wrote on Instagram, including the hashtags #PalestinianThobe and #ForMyYama (Arabic for mother).

Palestinian women traditionally wear hand-embroidered gowns. Each gown's embroidery is unique and represents the city that its wearer is from. For Palestinians, it is considered a way of showing pride in one's heritage.

Tlaib is the daughter of Palestinian immigrants from Beit Our al-Foqa, a village in the West Bank near Ramallah.
