Herchcovitch's so-called "beauty denim," which he says harnesses body heat and turns it into infrared rays that stimulate cellulite-combatting micro-circulation, made its debut at the designer's winter 2014 show at Fashion Rio, Rio de Janeiro's four-day fashion extravaganza, which wrapped up on Saturday.
The jury is still out on the veracity of the Sao Paulo designer's claim to have produced the world's first anti-cellulite denim. Herchcovitch says five years of research into the product shows it is effective, but medical experts have cautioned there is no miracle cure for cellulite.
In skinny jeans and cat suits made from a patchwork of indigo and grey denim with a metallic sheen, the models looked like tough, street-wise urban incarnations of medieval knights in suits of armor.
The skinny jean cum pleated skirt combos looked like what a 21st century Joan of Arc would wear, while the high-impact eyewear oversized sunglasses in the shape of ski masks conjured an urban knight's protective visor.

Besides "beauty denim," the other material of choice on Rio's catwalks was suede. Hand-painted or laser-cut, in earth tones or eye-popping hues, plenty of it was on display at the winter 2014 shows, which opened under unusually chilly and drizzly skies for the southern hemisphere's spring.
The collection also included plenty of the kinds of hand-painted pieces that have become her hallmark, including bellbottoms and skirts that bloomed with a multicolored riot of wildflowers. The highlights of the strong collection were the suede mini-dresses and fringed jackets emblazoned with oversized Hopi Indian Kachina dolls.
