First Lady Michelle Obama took the stage at the Democratic National Convention Tuesday night wearing a stunning pink and grey silky-like dress custom-designed by Tracy Reese.

Mrs. Obama wore the sleeveless dress with pink shoes, her hair loose and grey manicure. Common associations in Western culture with the color pink are romance, the blush of a young woman's cheeks, happiness and lightheartedness while grey is associated with balance, sophistication, neutrality and uncommittment.

"So honored @MichelleObama is wearing @Tracy_Reese for tonight's speech #DNC2012 ," wrote Reese on Twitter tonight. "Thanks everyone for sharing this amazing moment! We are all so grateful and honored to have dressed Mrs. Obama for such a momentous speech!!" she added.

The First Lady's dress was a big contrast from the bright red Oscar de la Renta dress Ann Romney wore at the Republican National Convention last week. Red is most commonly associated with passion, anger, vigor, love and danger.

Mrs. Obama's insipirational speech focused on trying to remind the voters about the man who charmed them four years ago. She recalled how President Obama has remained the same since she met him and talked about her deep love for him and his deep love for the country. 

"Being President doesn't change who you are. It reveals who you are."

Mrs. Obama also talked about the President's early struggles in life and how he reads letters from citizens and remembers what is like to struggle.

"I see the concern in his eyes...and I hear the determination in his voice as he tells me, 'You won't believe what these folks are going through, Michelle...it's not right. We've got to keep working to fix this. We've got so much more to do,'" Michelle Obama said tonight to a standing ovation from the audience.

The audience praised Mrs. Obama's speech and many African American women were in tears.

Mrs. Obama is expected to deliver a couple more of speeches at the convention in Charlotte, North Carolina, and attend the closing event Thursday where President Obama will accept his party's nomination for the Presidential candidacy.
