When practicing yoga or other fitness exercises I like to be in the correct attire for the occasion. I like my gear to fit snug yet breathable at the same time. This keeps me from being restricted due to my wardrobe malfunctioning or getting to hot. Most yoga tops are your standard look with just a different design on them. Ever bend over mid workout and your back is showing? It happens to me with many of my standard tops so I try to get long torso tops.
