I originally ordered a S/M as I am a solid Medium in popflex tops. And I was swimming in it lol. Not "cute but oversized" more like...well, you get the idea. I was about to return it, thinking that not even a smaller size could help with the proportions but I gave it a second chance. The XXS/XS somehow works. I have the cloud hoodie and I love the billowy sleeves on that and this is similar. The only struggle I'm running into with this is that the end of the sleeves use a ribbed material and my fitbit bunches it up a bit. Totally not a big deal, but thought I'd mention in case that bothers someone. The fabric is very soft. I have noticed that if you get water on it, it takes a very long time to dry. I will say, this is probably not a going out top for me. It's a work from home zoom top because it does look more professional than a hoodie. The bookworm blue is beautiful. I almost regret not getting the pink but you know what, if I'm going to live in this all winter, then I'll just have to order another one haha. Great design, Cassey, but the sizing was funky. I recommend sizing down! For context, I'm 5'9", 150 lbs with a straight/athletic body type.
