Michelle Obama's Tracy Reese dress was a hit at the DNC on Tuesday night.

The first lady is no stranger to rave reviews for her fashion choices, and the Tracy Reese dress she wore for her big speech at the Democratic National Convention is another fashion home run to add to her list.

The gold and pink dress showed off Obama's renowned toned arms and modestly cut off at her knees. She wore cute pink pumps from J. Crew and went with a trendy gray-blue nail polish for her nails, the Associated Press wrote.

The designer of the dress, Tracy Reese, described it is as a "silk jacquard in an abstract baroque wallpaper pattern" with a hot pink bodice wrapped with gold.

According to the Washington Post, Reese envisions Obama's body when designing a dress.

"There's a certain type of silhouette that is really flattering with her figure," Reese said. "She's tall and lean and curvy through the hips, so I'm always thinking about that."

The Associated Press reported that in an email, Reese said the first lady "looked incredible and spoke beautifully; I am so honored that she chose to wear one of my designs for such a memorable occasion."

Convention viewers took to Twitter Tuesday night to comment on the first lady's stunning Tracy Reese dress, which reportedly coat $4,000.
