I have seen this different times among American celebrities caught by the lens of a paparazzi's camera. But now that some African ladies are involved in such I have to ask this question, or is there something I should know that I don't know? Personally I feel it is unhygienic for a lady to step out of her house without her undies, and till this very minute I still don't know the reason for this or why some ladies engage in such act. The most annoying part among those that are involved in such act are ladies that sometimes perform on stage.
I have seen American celebrities caught unaware by a paparazzi's lence while performing, not realizing that their private part is exposed to the full glare of the whole world. At other times it happens when they are stepping out of their limos and there before your very eyes you see the private parts of these people. Serena Williams comes to mind here. The pics in this article of an African lady performing with her private part in full glare is just plain gross. For whateever reason these people are doing it, they should please stop it because it is not putting women in good light (I think). There is a reason why Panties are made and even if your excuse is panties makes you feel warm, there are so many different types out there and I can bet you will be able to find one that suits you just fine.
