I love this set because you can absolutely wear this to a party or just around the house to feel like the fanciest person alive. I found the cardigan to fit true to size. I did not try on the pants in person, but have tried on other sweater pants from this brand and do find that they also fit true to size. When in doubt with their pants, though, I go with the larger of the sizes if I’m in between. LTKSeasonal LTKHoliday LTKTall
