I may have a lot of bad luck in my life, but Op-shopping is not one of them.
Went on a little thrift trip last week for over-sized jumpers, my fave was this Lacoste chemise for a few dollars. So comfy i've already worn it multiple times! Also found a couple Ralph Lauren Polo's in mint condition i instantly bought for my dad. I suggest to everyone regularly check your local thrift stores, you never know what hidden treasures you can find!
