Ivanka Trump promotes Donald ... and the Ivanka Trump brand

It appears that Ivanka Trump's introduction of her father, presidential nominee Donald Trump, at the Republican National Convention on Thursday night, served more than one purpose.

The business-savvy real-estate-exec-slash-fashion-designer used the Cleveland, Ohio, stage to show off a blush dress from her namesake collection. Then, on Friday, the label's Twitter account posted an image of Trump wearing the frock, with a link to purchase a similar item on

That is the same retailer her father has faced off against in a head-to-head battle that started last July, when the department-store chain stopped carrying his menswear line. Macy's said at the time that it was "disappointed and distressed" by remarks the candidate had made about immigrants from Mexico.

Trump countered by saying it was his decision to stop selling his label at Macy's, adding that he has "never been happy about the fact that the ties and shirts are made in China."

Macy's continued selling Ivanka's line through the controversy. That decision seems to have panned out for the former model, as the sheath dress her label posted to Twitter sold out hours later on the company's site.

This isn't the first time Trump has used her father's political aspirations to promote her own clothing line, including a white floral dress she wore earlier this week. Along with Macy's, the designer's line is also sold at retailers including Nordstrom and Lord & Taylor.

The promoted blush dress was also listed as not available on Nordstrom's website. A black version was available at Lord & Taylor.

Correction: The Ivanka Trump brand promoted a similar dress to the one she wore Thursday night.
