How our sizing works

At Lillies Dream, we design with growing children in mind. Each size is carefully proportioned to provide a beautiful fit today, with room to grow and enjoy each piece for longer

Our sizing follows children's changing proportions, with thoughtful attention to garment lengths, widths, and adjustable details. Many of our designs feature adjustable straps, generous hems, and other details that extend their wear

Choose your child's size based on their current height and measurements, rather than age alone. Our sizes are designed with room for comfort and growth, so sizing up isn't always necessary

For the most accurate fit, use the chart below and compare it with the garment measurements provided on each product page
