My "everday" panties are Victorias Secrets microfiber panties and briefs.
I have them in just about every color. Black, Gray and White are less obvious to be "womens" panties, but all of the other colors are more obvious to be "womens" panties. They feel feminine, feel comfotable, and they hold everything in place. I also have them in thongs too. If I chose to wear something a lot more feminine such as my lace boyshort tangas, I sometimes wear a thong underneath them to hold everything in place, so I can get the sexy feel and look of the tangas, without anything falling out.
