Well being classified as a small endowed women... I wear it for all the above reasons listed. Also there is still enough there that when I run and stuff it does not feel comfortable moving around. The little bit that's there need to be shackled down! As far as regular clothes. It makes a shirt look better with a bra on under it over just seeing a girl's nipples through the shirt. It is a sense of decency. Also, yes the wonderbra can enhance what is already there and make them look fuller. Why does a guy with a small dick where underwear? Well I'm sure it would bounce around the sameway if he were running. Need to shackle him down.
