'75 Hard Style Challenge': the challenge that proposes creating fashionable outfits for 75 days without making a single purchase. With more than two million views on TikTok and more than 4,000 posts under the hashtag #75HardStyleChallenge on Instagram, the idea has reached far beyond its own followers.

The main rule is not to buy anything at all in the 75 days that the challenge lasts. The important thing is to create outfits that you yourself feel comfortable in without taking trends into account.
