Mexican politicians have new reason to be cautious.

The fashion police are watching.

Over the last few months, social media users have been hunting for designer labels, luxury watches and other hints of wealth on Mexican politicians, asking — even in a country where many are jaded by corruption — how could public servants afford such apparent luxuries?

“There’s a disconnect between the official discourse and the lifestyle of the politicians,” said Jorge García Orozco, a high school teacher and journalist who has built a growing social media following by showcasing the lifestyles of Mexican officials and questioning how they can afford them on government salaries.

“Many citizens, myself included, were fed up with the ruling political class,” he said.

Garnering over 100,000 followers on his X account, Mr. García Orozco’s work exploded in popularity this summer. Many of his posts started with online tips from people acting as what he called the “fashion police for politicians.”

The attention has also made him enemies. Gerardo Fernández Noroña, a senator who has been featured in his posts, has called some of his work “despicable” and accused him of working for the government’s opponents.

In an interview, Mr. García Orozco, 37, denied that accusation and said he was actually inspired by remarks once made by the man who founded the senator’s leftist party, Morena. He recalled being a teenager and hearing the founder, Andrés Manuel López Obrador, rail against corruption long before riding a wave of populist energy to the presidency in 2018.
