Blouse - Im wearing a size XS and it fits perfectly. I’m OBSESSED with this blouse. It’s so dressy and effortless. Pants - I’m wearing a size 8 as the 6 were out of stock. Sometimes I can get away with a size up but they are very true to size so I will need to return them and wait for a 6 to come in stock LTKstyletip LTKshoecrush LTKfit
