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.

One Marylebone Built in 1826 on its own ‘island’ in the heart of the capital, One Marylebone has rapidly become a firm favorite for event organisers and private clients looking for an elegant, yet flexible venue.

Beautifully refurbished to the original designs of Sir John Soane, the Grade I listed venue boasts 3 unique spaces plus landscaped garden, moments from Regents Park. The grandeur of One Marylebone has attracted blue-chip brands from a variety of industries with a focus on fashion, beauty and the arts.
