    Adorable Clothing

    The clothing is adorable but runs a tad small and shrinks in wash. That was my experience.

    Amazing Quality

    This outfit is adorable, true to size, and washes better than any of the other baby brands I have purchased. No pilling or fading, even though my baby wears it all the time. I love Pehr's quality!

    Cutest onesie!

    Love the practicality of the kimono style buttons! I can’t stand the over-the-head onesies and these are so easy! The fabric is thick and soft, clearly very good quality. It’s been washed several times and still looks like new!
