Lego Big Boys' 4-10 Chima Pajama

I purchase ft here for my 6 year old who is obsessed with Chima and have it saved for a surprise. It's so cute, and sizing runs about the same as all pjs shaped like this (I usually go a couple sizes up, did the same in these, and they fit comparable to all other brands I've tried). I'm so excited to surprise him with it- he'll be thrilled!!

This is smaller than a size 6 and 100% cotton.
