I’m in a M in this cardi. We both loved this one! Can be dressed up or down and the color is so pretty! Fits TTS. Jess is a size S in the block sweater. Definitely an oversized fit so you could Totally size down. Also my basic white tee is a staple! I have several colors! Very flattering and runs TTS LTKstyletip LTKfamily LTKSeasonal
