[2] Thùy was born and raised in the commune of Thiền Lâm, Tĩnh Gia District, Thanh Hóa Province, Vietnam.
With no personal contacts, she sent her portfolio by email to all the designers participating in Autumn/Winter 2014 London Fashion Week via any channels she could find.
She first heard back from Jean Pierre Braganza and proceeded to successfully book 4 shows that season, which was a turning point in her international career.
[11] The same year, Thùy made an appearance on BBC One's The Clothes Show and was the only Asian model in that edition's cast.
Thus, Hoàng Thùy has a chance to represent Vietnam at Miss Universe 2019 if the pageant is held sooner than the country's selection that year.
