Appearance
I was really impressed with the design and appearance of the panties. They're just as see-through as the sample pictures show. The designs are simple, cute, and don't get distorted when worn. In addition, the opening at the crotch was large enough to be useful without being excessive and tacky.
The sizing is also well done. A small/medium will fit 25" waist without any issue and they'll easily stretch a little bit to fit a 27" waist. Although they small would most likely stretch even further, getting the medium/large pair would be a better investment for comfort.
Comfort wise, they're fantastic for wearing for a few hours by themselves or for a short period under clothing. For under clothing wear, either a skirt or loose pants would be a better idea, since you'll get some nasty chafing otherwise. As long as you stick to that, they're quite comfortable and you could easily wear them out without trouble.


Materials and Cleaning
The panties are made of a nice mix of nylon and spandex. They stretch to fit without feeling too snug or itchy in any way. They came out of the box spotless, so there were no odors or rough spots.
For cleaning, wash them in cool or warm sudsy water. Avoid using scouring agents or high heat, since both can cause permanent damage. They've held up nicely to hand washing in warm water without any rough spots or odors.

Packaging and Storage
The package is the standard simple cardboard box with the panties wrapped in plastic. There's no reason to keep it around. The best option is to recycle the packaging and keep them in an underwear drawer or other discrete place. It's pretty clear what they are, so you may want to keep them in a discrete place.

These are still a lot of fun. They still fit comfortably and get a decent amount of use. They are definitely worth a buy.
