She returned to Cyprus in 1991 and established her own company under her own label, ES – ELENA STRONGYLIOTOU, creating wedding and evening gowns with her unique style; modern yet luxuriously elegant and attention to detail, she managed to set herself apart, identified as a serious haute couturier. In 2005 she participated with huge success at the “SPOSA ITALIA COLLEZIONI” exhibition in Milan. Elena was awarded woman of the year in the category Fashion Designer of the year, in 2006 by the readers of Madame Figaro magazine in Cyprus. In both consecutive years, 2006 & 2007 she made a huge contribution to the Breast Cancer Awareness Campaign by designing the official t-shirt and all the proceeds went to Europa Donna Cyprus.

In April of 2007 Elena created her first Pret a porter collection, presented by Mercedes Benz, “APO ASPRO SE MAVRO”, “FROM WHITE TO BLACK” of dresses and presented them by organising the first of its kind fashion show in Cyprus that took place in a timber warehouse. The response from the media was overwhelming; “It is the first fashion show in our country of such professionalism and of such high standard” as it was characterised.

In April 2008 she showed her third Pret a porter summer 2008 collection, “METAMORPHOSIS” presented by Mercedes Benz. Elena pioneered once again organising a fashion show in the municipality`s market place in the old town of Nicosia. The metamorphosis from a basic market place into a glamorous fashion event was astonishing.
