Which Dragon on the BBC show Dragon's Den founded the lingerie brand Ultimo?

Michelle Mone founded the lingerie brand Ultimo and later became a Dragon on the BBC show Dragon's Den.

Mone launched Ultimo in 1996 after developing a gel-filled cleavage-enhancing bra. The brand attracted attention for combining a fashion-led appearance with structural support, and it became one of the best-known names in British lingerie during the late 1990s and 2000s.

Mone joined Dragon's Den in 2015, serving as an investor for one series. Her appointment followed a career in design, branding and entrepreneurship rather than a background in the retail businesses associated with several other Dragons. Ultimo is sometimes confused with the businesses founded by other female Dragons, but the brand's founder is specifically Michelle Mone.
