Personal hygiene can be surprisingly confusing when nobody ever teaches you the basics. Bras are particularly tricky because they may still look clean after several wears, and unlike underwear or socks, there is no universally obvious rule telling you when they need to go into the laundry.
That uncertainty led one 17-year-old Redditor to ask the internet for some sisterly advice. She explained that she normally wears the same bra for around five days, sometimes stretching it to a week if there is no noticeable sweat, odor, or dirt.
She had never experienced skin problems and assumed her routine was fine until she saw someone with a similar habit get heavily criticized online. Suddenly worried that she had misunderstood basic hygiene, she asked Reddit what was considered normal. Scroll down to see what people taught her.

Sometimes embarrassment comes not from doing something harmful, but from suddenly discovering that other people follow rules nobody ever taught you. For this 17-year-old, a TikTok comment section transformed an ordinary personal habit into something she felt ashamed of. Yet her question deserves practical guidance, not ridicule.
The OP had developed a straightforward system: wear a bra until it smelled sweaty or appeared dirty, usually around five days and occasionally a week. She had never experienced odor or skin problems, so there was little evidence in her daily life suggesting anything needed to change.
Psychologically, that makes sense. People learn many hygiene routines through family observation rather than formal instruction. When that guidance is absent, they naturally create habits based on visible consequences.
What hurt here wasn’t simply learning that her routine might be different from others. It was realizing there was an unwritten expectation everyone else seemed to know.
Interestingly, the internet’s “fresh bra every day or you’re dirty” response isn’t a universal medical rule either. Someone exercising heavily in humid weather may need a clean bra much sooner than a person spending several cool, inactive hours indoors. Sweat level, skin sensitivity, activity, fabric, and duration of wear all matter. Hygiene is contextual rather than a morality test.
Dermatologist Alok Vij, MD, explains through Cleveland Clinic’s guidance on washing bras that a reasonable general guideline is washing a bra after about two to three wears. A short period of wear with little perspiration may not even constitute a complete “wear,” whereas several sweaty hours could effectively count as more than one.
Bras also collect body oils, dead skin cells, and perspiration, which can encourage bacteria and yeast and eventually contribute to irritation, rashes, odor, or localized infection. The American Cleaning Institute similarly recommends two to three wears and suggests giving bras a rest day between uses.
That makes the OP’s five-to-seven-day routine longer than the usual recommendation, but it doesn’t justify strangers labeling her “dirty.”
A better adjustment would be keeping several comfortable bras in rotation, allowing each one to rest between wears, and washing them after roughly two or three normal uses. After significant sweating or exercise, changing sooner makes sense.
Most importantly, she shouldn’t carry shame away from this experience. At 17, asking a basic question because nobody taught her is evidence that she’s trying to take care of herself. She received new information, took notes, and changed her routine.
That’s exactly what learning looks like and probably a far healthier response than turning somebody else’s knowledge gap into entertainment.
Let’s dive into the reactions from Reddit:
These Redditors recommended rotating bras to reduce wear, moisture, and frequent washing.
This commenter jokingly realized the discussion was a reminder to finally wash their bra
This group preferred a fresh bra every day because of sweat, heat, or skin concerns
These commenters said wearing a bra for two or three days before washing is perfectly normal
These users washed bras far less often when they stayed dry, odor-free, and were only worn briefly
So, where does everyone land, fresh bra every morning, a rotating lineup, or the legendary sniff test? And how many people quietly realized their favorite bra is overdue for laundry?
