Miranda studied fashion merchandising in Florida before building her label from menswear outward. She designed under the Xango brand from 1995, launched a Colombian menswear casual line in 1994, and put her own name to her menswear in 1997, opening her first boutique that year. In 2000 she crossed into womenswear with City People — embroidery, fitted trousers and transparent blouses — and a 2001 collection inspired by the novelist Gabriel Garcia Marquez.
She has shown at Colombiamoda, Colombia's national fashion trade show, and built a brand that travels well beyond it.
