Customer photo review of Playful Hair Clips (Set of 5)

Clips are vibrant in color and they stay on! My daughter has finer hair & these clips have stayed on throughout the day. They really pop on some color & are quite unique looking. I haven’t seen anything like them.

Customer photo review of Denim Overall Dress

Hello, I received my order yesterday, which included a sundress. My order number is MC-0010729240. Today, after the first wash, I tried to unfasten the snap buttons to put the dress on my child, and one of the snaps came off immediately the very first time I opened it. Could you please advise what I should do in this situation? I have attached photos. Thank you.

Customer photo review of Recycled Cotton Pattern Baby Ruffle Dress

I am absolutely in love with this Dress! The pattern is incredibly cute and unique—it really stands out from the typical baby prints you see everywhere. Plus, you can feel the quality immediately. It has all the premium fabric and finishings I’ve come to expect from Mon Coeur. ​ ​The colors are a little more subdued in person than they appear in the website photo, which I actually think gives it a really sophisticated, high-end feel. It's also worth noting that the small embroidery label doesn't have a protective backing, which might be a consideration for children with sensory issues. However, the "MC" logo is quite small and the dress is fluffy enough that it shouldn't be a problem for most little ones ​Overall, it's a beautiful, sustainable piece that feels like it will last!

Customer photo review of Recycled Cotton Confetti Kid Sweatshirt

I love this Mon Coeur sweat combos! My daughter is top percentile for height and constantly going through growth spurts so I tend to buy a bit larger. …as most parents right? However, I absolutely HATE the disheveled look that comes with buying ahead in kids clothing but this is where Mon Coeur comes in! The pants are snugger than sweats but not quite as tight as legging allowing for clothes to still be worn across sizes bc it doesn’t pull at the legs and also fits appropriately around pullups/diapers. I prob wash my toddler clothes more than needed bc of how active we are but these sweats have not yet shown any signs of fading or shrinking.

I absolutely love this and other outfits I have. They are super soft and keep her nice and warm. The quality is very good, definitely hand wash to keep in good condition. I liked this sweater so much, I ended up getting the next size up 6-12m.

Customer photo review of Kid Mon Coeur All-Over Sweatshirt

The sweater feels a bit stiff at first, but once you wash it, it is super soft. I love the quality; it's very durable and feels like it will last a long time. It's the perfect thickness as we're transitioning from a cold spring to summer! The 2-3Y fits my 13 month old pretty perfectly. He is 33''.
