Clothes need to fit; ill-fitting clothes are awkward and can be uncomfortable. Customers know this, and so they shop in stores instead of online, where they can try before they buy. When it comes to garage sales, the fact that they are only paying a dollar or two may prevent customers from being too cautious about sizing and proper fitting. However, if you are selling a lot of clothes at your yard sale and want to make it easier on customers, why not construct a makeshift changing area so they can be assured that what they take home will indeed look good on them?
Tall wooden or cardboard partitions will easily section off a private area of the garage or a spot against your house. You can construct these yourself for cheap, from scraps, or you can try and borrow some from a neighbor or friend. Alternatively, any sort of decorative partition will work, so long as it is tall enough for people to safely change behind it. If you don't have access to something free-standing, you can always suspend a sheet diagonally across a corner of the garage.
For a really makeshift changing area, you can hang a hula hoop from a tree or the eaves of your house and drape a sheet around the whole circle. This will leave a slit for your customer to enter and exit the "dressing room." While this does provide privacy and allows the customer to see if the clothing fits comfortably, there is no place to put a mirror. Also, the cramped space is uncomfortable, and will get hot during the heat of the day, so unless you're desperate for space, this may not be the best way to go.
If you're going to bother with a changing room, it's really a good idea to put up some sort of mirror. Preferably, you can hunt down (or you already have!) a full-length mirror, or at least one that will provide the customer with as much of a view of themselves as possible. If all you've got is a small mirror, don't hang it at head height -- even though that will seem awkward to the customer at first glance. Hang it at about chest height, so they can back up and see more of the outfit or article of clothing.
Customers may be leery of using the changing room for fear of privacy invasions. These may come in the form of curious children, poor changing room construction, or even (but hopefully not!) creepy visitors. One way to reassure your customers is to put the changing area near the sales table and tell them you'll be on the lookout. Turn your chair away at an angle that could not possibly peer into the dressing room, then seat yourself and keep an eye out for intruders. You can also set up the room behind a closed garage door, or have a double-layered entrance to prevent it from falling apart and exposing the unwitting customer.
