I'm surprised this is an environmental and thrifty tip.  It's hard for me to imagine what goes on in the mind of someone who DOESN'T rewear.  I have heard tales of people who only use a clean towel once and then throw it in the hamper.  That is mind boggling!  Aside from the other wastes created (water, detergent, etc) there must be a huge time expenditure.  I have better things to do than to do laundry every three days.  I even rewear things that I've worn to the gym.  I just leave them out to air dry overnight and wear them the next time I go.  I'll do this for three wearings or so.  My husband does it, too and I see other people who regularly go the same time as us wearing the same things a few days in a row.  The whole gym smells like sweat anyway!

I guess I'm in the minority but I find it repulsive to re-wear.  Fact is I feel clean when I know my clothes are clean.  Sorry, but theer is a limit.  If you have to smell it, throw it in the hamper.  

Why not get a 2nd day out of a shirt or pair of jeans?  Hey, don't most of us re-use our tooth-brush?  Got news for ya, there's a lot more nasty germs in the toothbrush then a worn shirt that you've not sweat in.

I regularly wear jeans or a shirt twice.  It's amazing how you can throw jeans and/or shirts in the dryer to remove the wrinkles.

Down here in the drought-ridden southeast, I suspect that the soon coming extreme water restrictions might make some folks have to, gasp, stretch their clothing usage a bit.  

I'm a student in Tucson, AZ, so there are not many days when this works with everyday shirts (even in the winter, the sun is strong and makes you sweat, and my office and my classes are at opposite ends of the campus). But for almost everything else,  I rewear them a couple of times.  Pants rarely get dirty the first time you wear them, outfits I wear just to go out at night almost always stay clean (hooray for the smoking ban) unless I've been dancing, and who cares if the clothes you are wearing to clean the bathroom or vacuum the floor are not freshly laundered?  People have the same misconceptions about re-wearing clothes as they do about showering everyday- washing clothes every time and showering every day is not good for the clothes or your skin unless they are actually dirty.

I have hung up a lot of those shelves with pegs or hooks in my bathroom and bedroom.  In the bathroom I hang my towels and they look nice, are easy to grab and dry out quickly. In the bedroom, after wearing a piece of clothing, I hang it on a peg-so I know it's been "used" at least once.  When I dress, I peruse the hooks first and wear those items if it fits the need.  So at any time my hooks will have a pair of jeans, shorts, t-shirt etc. This is great for kids-doesn't require fussing with folding and looks much neater than on a chair, bed or floor. Then when doing laundry, if I don't have a full load, I can quickly scan the pegs for something that is probably due, and give  the towels a quick sniff for readiness for a wash.   As for my washer, I learned the hard way not to use cold water in the hot steamy summer (I don't run the air conditioner much).  If the toilet is sweating (even with the antisweat liner installed) then I use warm water in the washer.  The outside tub of the washer also sweats if I use cold water, and it dripped on the motor and other parts, and everything rusted out.  

I have to laugh at some entries. You wouldn't believe how far the time between laundry loads  can be stretched. I can attest to that fact, even living in a tropical island! As a graduate student, I once had no time for the laundromat marathon, so I wore my clothes for 3 weeks (that would make 4 wearings per piece). Did my classmates, professors and co-workers run away to hide form the stench? No, and the reason is, there was no smell. I hung my clothing to "air" and problem solved.

I can believe that people wash clothes after 1 use or try-on..  As a single guy, I can go at least 2 weeks before I have to do wash, I dont wear under garments or socks more than once, but dress shirts at least 2 or more wears and jeans can go for at least a month.  They key is to have play jeans, going out jeans, lawn jeans etc etc etc..  Save the planet people!  

I wear my pants at least 2-3 times before they get laundered.  I have a favorite pair of jeans and tee shirt that gets worn every evening.  When I get enough stains on it for the week it goes into the laundry.  Give your clothes a break.  Less washing means you'll have them longer.

I totally agree with the author.  I take a bath every day, so I don't feel that my clothes get dirty after wearing for only a few hours a day.  Plus, I try to buy nice clothes that I want to keep a while, so they last longer and look nicer if you wash or dry clean them less often.  And for you people out there that disagree, do you change or wash your sheets on your bed every single day?  Probably not.  Even high-end hotels don't do that anymore if you stay more than one night in the same room.  Do you wear a different pair of shoes every single day?  Probably not.  (Actually, you should have two pairs of everyday shoes so you can alternate and air out a pair every other day.)  If you think about it, some things we have done out of habit in the past don't make that much sense.  Wearing your clothes more than once before laundering them makes sense for preserving your clothes, your pocketbook and the planet.

My method for getting more than one wearing out of a piece of clothing, is layering.  This is practical too.  I'll wear a t-shirt under a sweater, then I don't have to wash the sweater and can wear it a few times.  The same goes for an oxford.  I even do this with polos.  Then I can wear the same t-shirt to exercise later.  Whatever gets worn as the upper layer can go with out washing much longer.

I am a bit overly endowed, so when I exercise, I often have to wear more than one bra.  I always wear sensible bras -- nothing fancy, lace or silk.  If I wear a bra to work one day, it goes into the pile to be part of my double set for my next workout.  Same can go for sweat socks (which I wear almost every day). If I wear a pair to work, I don't wash them until I've also worn them for a run or workout.

Also, I quikcly wash or rinse my bras in the shower.  They last longer that way!
