Ivanka Trump Wears $138 Dress She Designed to Introduce Donald Trump at RNC

— -- Ivanka Trump's marketing chops were on display at this week's Republican National Convention -- literally.

While stepmother Melania Trump opted for a $2,190 designer dress when she took to the RNC stage in Cleveland Tuesday, Donald's entrepreneurial daughter wore affordably-priced pieces from her own fashion label. The Ivanka Trump Collection is sold at major department stores, including Macy's and Nordstrom.

On Thursday night, when Ivanka, 34, introduced her father, she sauntered onto the stage wearing a $138 blush-colored sleeveless sheath dress from her own line, according to "Women's Wear Daily."

And on the previous night, the style-savvy mother-of-three also culled pieces from her collection: A $158 off-white dress and a $135 pair of black suede pumps.

But it's not surprising Ivanka wears her own pieces. In an interview with "Teen Vogue," she said, "In working on my collection, I really designed only things that I personally would love to wear. Quality for me is key, and this stands true in every facet of my business from real estate, hotels, and fashion. I love to travel, so I often draw much of my inspiration from every city that I visit."
