5. You don’t take care of your clothes.
“Her shirt was worn around the elbows and she just looked unkempt.” You may not be able to buy new clothes every time you go out on a date, but you should take care of what you have by ironing, mending, and removing lint. Neglecting these small steps makes you appear slovenly. Also, try not to wear the same thing over and over again. You’ll give the impression that your other clothes are unwashed.
