Since a regular shirt would have looked far too big on me, I decided to go for one that's a 'slim fit'. If you're on the skinnier side like me, then you should do the same. I then paired it with a pair of grey tights to keep the look monochrome and minimal. A tiered necklace and brogues finished the look. PS: I wore my hair down so that the shirt didn't look bigger than it already was, since my hair covered the shoulders.
Okay, here's a rule of thumb. When you're wearing anything oversized, wearing a belt really helps. It immediately pulls in the waist and gives some shape to all the bulk. In this case, I did exactly that, plus I paired it with a metallic skirt so that focus shifts from my dark, bulky sweater to my pleated skirt. And it's definitely a look I would try again.
