Back in Time Long Sleeve Top

This is my first time buying this brand, and to be safe, I went with size 12 it fit well in the body (stretchy material) but the sleeves are to big or loose I think I should have order size 10 ,my weight 170 pounds sometimes I wear 42D or 42C bra,it depends but for my taste size 10 would have been better because the sleeves were too loose for me I hope my review help you
