Tess is Nona's twin and Yasmin's cousin. She is nicknamed Solo by her sister and friends. She has been produced 4 times (2nd Edition Twiins, 2nd Edition Babyz Twiins, Lil Angelz and 2007 Play Sportz).
The novel Bratz Clued In: Seeing Double reveals that Tess is very good at Art, and specializes in creating collages.
She has brown eyes and dark brown hair. Initial runs of Tess featured her with deep tan skin matching that of Spring Break Yasmin, but subsequent runs had her with a lighter tan skin tone matching the usual skin tone of Yasmin.
Tess is the "bad" twin. She is nicknamed Solo because she prefers to do things on her own.
