    These are my son’s favorite underpants. He prefers them more than any other brand he has.

    Cute but small

    Really cute for my son and he loves wearing them, but I’m finding they run a tad small. The sizing was 2-3 or 4-5, my son is 3 so I thought the 4-5 would be big for him but will definitely size up next time.
