Size 2 tunic from H&M, very very dark green/black

I love this tunic so much and yet it really just does not flatter my body like I thought it would, purchased from another posher recently. It is a very very dark green almost black color, lovely crepey silky type material, just gorgeous and in perfect condition, size too but would fit size 2 through 6. I would think with tights or leggings is the best way to wear but honestly, I am 5’5”and it hits just above the knee so it’s not too overly short. Enjoy, I sure wish it had worked for me!
