The shapelessness of oversized tops are also ideal if you're not the most confident about your body (me included). It's like wearing a gigantic pillowcase. You have a lot more freedom to move and it's useful for days when you feel like pigging out or it you're going to a buffet for lunch or dinner.
With oversized tops you get a very laid back look and they're my to-go to outfit for when I'm feeling lazy or if I'm just hanging out with my friends on the weekends. My hoodies are also too big for me for the exact same reason - comfort.
Tops like this also give you the freedom to wear whatever accessories you want. You can glam it up as much or as little as you want. Anything goes with anything since the look is so relaxed. It's kind of like an undecorated cake where the accessories are the icing and sprinkles and whatever else on top.
That's all for now. Stay beautiful x
