I’m always skeptical of ordering sets like these from Amazon because you never know if the fabric is going to be stiff or cozy. I lucked out with this one… it’s a cozy waffle knit type fabric that’s not too heavy and just what you want when traveling!! I would say it runs true to size but if you’re between sizes, then definitely size up one. I did size up to accommodate my growing bump! #LTKunder50 #LTKunder100
