Short Hair for a Round Face

Thanks Lynne Chapman, Thanks for sharing this links ,these link contain very informative information. I have got lot of information. Please keep sharing more and more information.

I don't but the weird thing is that when I pose for pictures I often look like I do. It mostly happens when someone takes a long time to take the picture, I am very shy so I am very uncomfortable while waiting for the picture to be taken and I also do not like to look at my pictures. It must be me tensing my face and body. I sometimes even look like I have two or three chins.

Nancy, I'm not very photogenic either. At least I never look in pictures as I think I should look.

These are 2 articles that talk about styles for different face shapes. The article in my first post has lost its images.
