This is a great burnout t-shirt. I am 5'6,at 150,c cup. I ordered size S and size M,and kept the size M,because size S on me had too fitted of the look for me personally, and i wanted a bit more of a loose but not too loose t-shirt look (kinda like in the products  picture).It's not long enougth to be a tunic or a t-shirt dress;it's more of a long/elongated t-shirt,but i think you can still wear it with leggings and it would look great,just not the see through leggings lol,but more of the pant legging type. It's also not too see through like some other burnout t-shirts/tunics; it's a little see through,where you can see a bit of a skin,especially if you have light skin,but not your bra,so you don't have to wear a cami underneath. It's appropriate enougth as a casual everyday shirt. I really like it :)
