Size Chart

At Mon Petit Chéri, we believe that dressing your little ones should be a joyful experience—one filled with tenderness, tradition, and ease. Our sizing guide was created to help you find the perfect fit, from newborn snuggles to playful 10-year-old adventures.

We know how quickly little ones grow, and how important it is to get the size just right. Whether you’re shopping for those precious first weeks or timeless pieces for toddlerhood and beyond, our guide includes helpful measurements for height, weight, and waist so you can shop with confidence.

Each of our garments is thoughtfully crafted to ensure comfort, durability, and a true-to-size fit—designed to move with your child and be cherished through every milestone.

If you’re ever unsure, we’re here to help. Our team is always happy to provide guidance, and our product pages include sizing tips for specific styles.

Because we believe children should look like children—and feel free to move, play, and make memories in comfort and charm.
