Wu, 33, became a fashion favorite after dressing FLOTUS Michelle Obama during the first and second inauguration of President Barack Obama. Since 2013, he's also the creative director of Hugo Boss's womenswear line.
He married Rangel, a chief financial officer at Wu' eponymous label.
Celebrity guests included the likes of actress Diane Kruger, fashion blogger Bryanboy, and art director Sofia Sanchez de Betak.
According to Taiwan's Apple Daily, Wu's mother Chen Mei-yun did not attend the event, but that didn't prevent all the guests to have a wonderful time, as evidenced by their Instagram feed: hashtag #RangelWu is giving us serious relationship goals.
