T-shirt - I’m wearing a size 6. It’s an oversized fit so don’t order to big. Pants - I’m wearing an 8, I wish I had ordered a 6 as I am a 6 so these are a little big. They fit okay with a belt so these pants are true to size. They are slightly long on me as they’re not petite and I’m 152cm. But I always like to roll the bottoms anyway. LTKfit LTKstyletip
