If you need a couture LEGO design, then Nathan Sawaya is the person you see. The brick master designed an Ahsoka Tano dress for Ashley Eckstein last summer, and he just made a one-of-a-kind jacket for DC President Diane Nelson. Sawaya made an elegant LEGO jacket for Nelson to wear to the premiere of The Lego Batman Movie. It is an ideal place for such a creative design.
The jacket features Batman, of course, and his arch nemesis the Joker on the front and the Bat-symbol on the back. This impressive jacket includes over 10,000 LEGO pieces (mostly two by two plates) and took Sawaya 100 hours to craft. You can view additional photos of the jacket at DC Comics.
