        ONEderful!

        We were lucky enough to bring our son home in a cardi suit from the hospital a year ago ( they are the cutest !) how could we not celebrate his first birthday with a bow tie one onesie. The bow tie stars are beautiful. We purchased an extra so my daughter can have a matching bow. The pants are great quality, the star knees are perfect. The one is thick and sturdy on the inside shirt. I love the Cuddle Sleep Dream brand. I will cherish the outfits forever !

        Looks amazing!

        We purchased this for our son's first birthday and it fit amazingly well! The shirt was so soft and even though he got food all over it, it cleaned up really well and we are wearing it for another party this weekend! I'm a forever fan now and plan to get more outfits from here as they are well worth the money!

        LOVED IT!

        I don't often write reviews, but I was so very pleased with this purchase for my son's first birthday. I was late to the planning process and ordered this outfit with the personalization option a week before his birthday. Ryann graciously communicated with me and promptly fulfilled my order. It arrived in time! Our photos are PRECIOUS, and I love that we can save the little bow tie as a keepsake from that special day. HIGHLY recommend, and I will definitely be shopping here again!
