By implementing Crêpe de chine and chiffon into airy garments that were both, elegant and adapted to everyday life, he soon made a name for himself with the subversive, surprise element each garment bore. Guy Laroche jazzed up the elements of seduction and minimalism that could be seen in his designs of - a simple black dress with a high neck and a bare back, a long skirt with an unexpected slit, a masculine jacket with a draped back.
Lorache's designs were and still followed by decades such as - the inventor of the sack dress impressed Women's Wear Daily with his ground-breaking 'lose lines'; his 'dos surprise', a taste for surprising, unexpected design on the back of dresses, charmed his clientele. His masculine suits entirely embroidered in black sequins proved a bold alternative to cocktail dresses; reversible knits and tiny berets, and knot-tied toques spiced up every woman's wardrobe. Creations such as the coat-dress and the shirt-dress continue to be a staple in women’s wardrobes today.
Monsieur Laroche's approach to the business was also modern: he presented shorter collections, not only in Paris but all over the world - Lebanon, Tunisia, Japan, Iran, Turkey. He wished to build personal relations with his customers round the globe. He passed away in 1989.
