1. Don’t re-wear undies
Most would agree that underwear should be washed after each wear. It's a simple rule when it comes to hygiene.
2. Jeans: after 5 to 6 wears
You've probably wondered how often you should wear your jeans before washing them. Washing jeans too often could result in ruining them and they may even lose their colors if you wash them too often. So the optimal number of wears is 5 to 6 times.
3. T-shirts and tops: after one wear
Treat your t-shirts like underwear because they are in close contact with your skin and they absorb the biggest portion of sweat. Wash them each time after wearing them. The only exception is when you wear them for an hour or less.
4. Dresses: after one to 2 wears
While you don't need to wash your dresses after each wear, twice is ideal. Washing them after just one time can ruin the fabric and its color especially if you are wearing a shirt under it. But if you were wearing a dress on a hot summer's day, it is better to wash it after just one use, as it would have soaked up lots of sweat.
5. Bra: after 3 to 4 times
Unlike underwear, bras need not be washed after each use. As long as you're airing it between each wear, you can wear a bra for 4 times. This does not apply to sports bras.
6. Socks, tights, and stockings: after every use
Socks host a lot of bacteria and dirt that you have collected with your feet, thus after just one wear, it is essential that you chuck them in the wash.
7. Sportswear: after each use
Sportswear should be washed every time after wearing it to the gym. It doesn't matter how long you were training, you were still sweating and touching different machines and devices.
8. Pajamas: after 3 to 4 wears
The smell of dirty pajamas can spoil your peaceful slumber making you feel tired. So, take care of your sleep by keeping your pajamas clean. Furthermore, it's best if you take a shower before sleeping, in which case you can use them up to 4 times.
9. Shoes: when they get dirty
Shoes should be cleaned each time they get dirty and according to their condition. Just be sure that you don't ruin them with water.
10. Skirts, pants, and shorts: after 3 wears
Skirts, pants, and shorts need to be washed more frequently than jeans. Usually after three wears.
