NEW YORK, Dec 19, 2010 / — “Something old, something new, something borrowed…” is the old adage about wedding. For the 21st century, “something green?” is becoming a popular add-on.

In a growing trend, more and more brides-to-be are saying “I do” to the environment. Industry insiders expect the trend will continue, especially given the worldwide interest in Prince William and Kate Middleton’s plans for a possible royal green wedding next year.

To help kick-off the 2011 bridal season, Eco-Beautiful Weddings magazine and The Cotton Bride announced the “Are You a Cotton Bride” contest at a fashion show featuring the latest in “green” wedding gowns from The Cotton Bride, the USA’s first collection of hand-sewn wedding gowns.

At the event, designer Chris Kole unveiled selections from The Cotton Bride’s new Fireflies Collection. The line helps brides keep it couture, while staying eco-friendly.

From the venue to the menu, some other top trends of 2011 include recycled or digital invitations, using local vendors and food, potting or planting centerpieces, opting for organic wines to toast or picking an eco-friendly destination like a ranch in Boulder, Colorado or oceans in Cape Town, South Africa.
