"I was trying to stretch boundaries for masculine and feminine; also there was something a bit science-fiction in the shapes," said Marongiu after the show's in Paris Grand Palais.
The result was a Paris collection with some great ideas, but one that seemed to lack energy overall in its 42 looks.
High notes were a series of sporty skirts that could be described as intergalactic tennis-wear. Cut on the bias, the techo-fabric had a voluminous and exaggerated natural flounce — appearing to float upward as it would in zero-gravity.
The science-fiction theme continued with an all-white shattered glass-effect zipper jacket and crossover top. It was achieved with fastidiously hand-sewn pieces of leather.
However, the grey fringing details that appeared on several ensembles and the white shirt and black masculine-tailored pant looks didn't feel very fresh.
Marongiu, it seems, worked best in zero-gravity.
