I just bought the cutest yoga pants! I really wish I could wear them at work though.
 Lululemon Wunder Under High-Rise Tights.
Is that a specific brand of tights or yoga pants?
Yoga pants stretch well and snug to our body in a way that makes them very comfortable to wear all day and night long. 
Yep. The snug fit is what I love most about them. They're especially good for outdoor activities.
This makes girls of all body shapes feel better about their shapes and boost their self confidence .
It definitely boosts my self confidence!
In short, the difference between leggings and yoga pants is that yoga pants are meant for athletics while leggings are not specifically designed for this purpose and may be too thin to wear during fitness activities.
Really? I didn't know that. I kinda assumed yoga pants and leggings might be the same thing, just different material.
One of the main reasons for your leggings rolling down is that you have not got the right size.
