Australian label sass & bide gives classic suiting a twist at London fashion week

LONDON - Sharp pant suits with sheer tuxedo tails, flowing gowns with thick metal harnesses — the new collection by Australian label sass & bide is a study in contrasts and classics with a twist.

The brand, by Australian duo Sarah-Jane Clarke and Heidi Middleton, showcased its futuristic spring runway preview at London Fashion Week on Friday.

Middleton, who wore a white cape and vest set from the collection at an interview before the show, said she wanted to contrast sensual lines with masculine strength.

The collection started with black and white cocktail dresses with origami fabric folds at the waistline, a design that appeared later on the neckline and on thick strips of gold-plated metal used as belts.

Variations of the white pant suit had a starring role: One had sheer sleeves, another had long flowing silk tails, and a third featured embroidered shorts. Dresses, on the other hand, were toughened up with strong geometric cut-outs, shiny gold trims and harnesses.

The monochrome palette was punctuated by bright oranges, soft shell pinks, and head-to-toe mirrored silver sequins in the evening section of the show.

Clarke and Middleton, both self-taught fashion designers, started their business selling customized jeans in London's Portobello Market before formally launching their label in Sydney. They have shown both in London and New York fashion weeks.

The brand now has 20 stores in Australia and is planning to open a flagship store in New York next year.
