Special effects typically are a feature of the runaway show — not the
dresses themselves. The Galaxy Dress, on the other hand, is one
spectacular special effect — the most dramatic evolution in 21st-century
fashion.
24000 full color LEDs, measuring a mere 2 by 2 mm in size, were used to
create this mesmerizing dress. The circuitry itself is hand embroidered
on a layer of silk in a fashion that permits it to stretch, allowing the
LED bedazzled fabric to drape with fluidity over the body.
To fuel the LED fabric, a few iPOD batteries illuminate the silhouette for 30 minutes to an hour.
Additional layers of silk chiffon diffuse the light, giving the gown a colorful jellyfish-like transparency .
When the digital patterns fade and the silhouette grows dark, more than
4000 hand-applied Swarovski crystals add sparkle and glitter to the
gown.

Celebrities tend to be on the cutting edge of
fashion as well, and at the recently concluded 55th Grammy Awards, the
beautiful Carrie Underwood graced the stage during her performance of
“Blown Away” and “Two Black Cadillacs” by wearing a unique “projection
dress”, which is a bespoke platinum colored satin gown from Theia. This
unique dress enabled a series of animated images to be projected upon
it, as though she was wearing a projection screen all the way.
