If you want a piece to look more high end than it is - try buying it in a bigger size. I love brands like Vetements or Acne Studios and how they play with dimensions, and you can usually get the same effect by just up-sizing. This knit is a good example. I tried it in XS and while it was slightly oversized it was still very boring. Tried it again in a M - bingo! Way too long sleeves and a boxy fit, just how I like it.
