Republican supporters criticized that Harris' move seemed to be a "tribute" to Obama and a "provocation" to Republican conservatives; American netizens who support the Democratic Party praised that Harris's dress taste and the design style of her campaign team were able to catch the attention of young people.

After Harris's appearance, the term "tan suit" quickly topped the trending search list in the United States on the social media platform X (formerly Twitter), and many netizens recalled a "dress scandal" during Obama's presidency.

On August 28, 2014, then-US President Barack Obama wore a very eye-catching light brown suit to participate in a defense meeting and meet with the media to report the details. The atmosphere of the meeting should have been very tense, and the topic of discussion was how the US Department of Defense should respond to the rapidly escalating regional situation in Syria, but at that time, people's focus was all on Obama's dress. Some media even invented the term "tan suit" by combining Obama's two campaign slogans ("The Audacity of Hope" and "Yes, We Can").

Although the suit Harris wore on the evening of the 19th was darker in color than Obama's, it was also brown in tone, which made many American netizens quickly think of the term "tan suit".

At the Democratic National Convention that opened on the 19th, Clinton, Hillary, Obama and other Democratic leaders all showed up to support Harris, and Obama delivered a "carefully prepared" speech to support Harris. Obama and Harris first met in 2004, when Harris helped Obama hold a fundraising banquet when he was still running for the Senate.

On New Year's Eve 2007, Harris, then the San Francisco District Attorney, left her warm California hometown and flew thousands of kilometers to cold Des Moines, Iowa. At that time, Obama was holding a rally in the Midwest of the United States.

At that time, the political bigwigs in the Democratic Party almost overwhelmingly supported Hillary, but Harris insisted on supporting Obama. In one interview, Harris stood next to a trash can in Obama's campaign office and told reporters: "The fact that we can gather here today is worth opening a thousand bottles of champagne and setting off a thousand fireworks."

Obama's successful election also paid off Harris's "risk", allowing her to make rapid progress in California politics and eventually enter the national political stage.

It is reported that during Obama's presidency, Harris entered the highest-level private gatherings of the Democratic Party as a local prosecutor many times. Both of them are of mixed-race backgrounds, and Obama and Harris' policy propositions attach great importance to social fairness and providing opportunities for disadvantaged groups. This time Obama fully supported Harris, and Harris also pulled Americans' memories back to the Obama administration with a dazzling "tan suit".
