The Strictly Come Dancing presenter looked smart as she suited up for a morning visit to the BBC Radio 1 studios in London.
Tess opted for a navy suit, sporting a tailored jacket with white cuffs along with matching cigarette pants which just grazed her ankles.
To go with her androgynous two-piece, the model wore a grey-blue shirt with a black panel running up the middle teamed with minimal silver jewellery.
She did add a slight feminine touch to her boyish ensemble by topping her pins with a pair of patent black courts shoes, completing her outfit with a structured white woven handbag with tassel detailing.
And while we often see Tess with her tresses styled in bouncy curls, this time she opted for a poker straight 'do, finishing with lashings of mascara and a touch of apricot lipgloss.
Tess is currently presenting Strictly Come Dancing on BBC1 alongside Claudia Winkleman, with contestants including The Saturdays star Frankie Bridge (née Sandford), 'Mama Do' singer Pixie Lott, TV presenter Caroline Flack and former rugby player Thom Evans.
