The white shirt is not quite a sweatshirt, but definitely thicker than a regular long sleeve! Love it for cold winter days. I’m in the small. Jacket is from Levi’s! If you see me in a jean jacket, it’s this one. I size down in it.. wearing the XS. I have these linen pants in white too and love how they fit. They are a bit roomy, so you could get away with sizing down if you wanted. I wear these shoes constantly because Emery isn’t home to take her own shoes! haha They’re so dang comfy. I am an 8-8.5 in shoes and get the 39.5 in these.
