Prince William and Kate Middleton announced their engagement on November 16, 2010, and when they did, fans paid close attention to what the famously fashion-savvy bride-to-be wore for the occasion. In this case, it was a blue jersey dress by Issa, a UK label designed by Brazilian-born Daniella Issa Helayel.
The designer told People magazine, "We are thrilled with the engagement news, and I'm very happy that she has chosen to wear Issa today." Helayel’s enthusiasm is justified; the label boasts such high-profile clients as Scarlett Johannson and Naomi Campbell, and Middleton’s choice of the dress increased the company’s already considerable standing. Issa plans to re-launch the brand in the U . S . , and eventually take it worldwide.
