Tulisa’s style has become increasingly demure and classic over the weeks on X Factor. For Sunday’s results show, Tulisa looked stunning in a classic black lace, waisted dress by Stephanie Allin.

Originally an award-winning fashion bridal designer, Stephanie Allin is renowned for her flawless fit and mix of demure detail and sensational style in her exclusively British made gowns.

Stephanie has a boutique in Marylebone, Central London and has recently launched an evening wear collection modelled by Strictly Come Dancing’s Natalie Lowe and Katya Virshilas at Harvey Nichols’ OXO Tower and One Marylebone.
