This is our first stevi short set and we are obsessed!! The fabric feels soft and breathable like bamboo but it’s slightly thicker and sturdier like cotton. And the smileys are adorable in person. :) I sized WAY up for my tall 2.5 and bought him the 5T, and I’m glad I did because it fits him perfectly with a little room to grow. I’ll definitely be back for more of these sets in gender neutral/boy colors!
