Looking for something lovely for your baby girl for summer? This little princess crochet baby romper is the answer. This crochet baby romper is so cute with the mono strap detail. Looks great in all girly colours plus it has an excellent fit.

DESIGN

This crochet baby romper is a very simple, yet unique design. It is worked bottom up, with the front and back panels made separately. It has a mono strap design and a beautiful ruffle detailing. This crochet baby romper is super cute and great for the beach.

BEGINNER FRIENDLY

The mono strap crochet baby romper is great for beginners as it uses simple crochet stitches to achieve this beautiful look. It also comes with a video tutorial to guide crochet beginners

EASY AND FAST

This crochet baby romper isn’t just cute, it is also very easy and works up super fast. It is great for quick baby gifts and you can be sure it will be a unique gift for a baby to receive.

MAKE IT YOUR OWN

You can decide to add an applique of your choice to your own crochet romper. I added a heart embellishment to the first one I made. I did not add any applique to the second one.

I used Dk weight yarn for this easy crochet baby romper pattern. You can use any Dk weight yarn of your choice.
