Pattern Details

This open back a-line dress pattern is completely reversible and comes in sizes newborn to 12 years.

A very simple, easy to sew pattern, it’s suitable from beginner sewing level. The back is open so it needs to be worn over a diaper cover, bloomers or shorts. It ties at the back with fabric ties and has ruffles along the center back seams and hem. It is fully reversible so you can pick a contrast fabric for the lining and change it every time your little girl wears it!

With color step-by-step photographs and detailed instructions it is suitable for every sewer from beginner to advanced. The sewing pattern can be printed as many times as you like so you can make a whole range of dresses in different fabrics if you wish to.


All the seams are cleverly designed to be self-finishing. This means all the raw edges are neatly tucked away out of sight. No overlocking or serging required… and no fraying fabric for little hands to pick at! That said, if you have a serger, tips are included for when and where to use it if you wish to.

The PDF tutorial includes clear descriptive photos for every step, computer drawn printable pattern pieces for sizes newborn to 12 years, instructions on how to cut the pattern out and simple, step by step instructions to complete your dress.

    I love the detail the ruffle adds. My favorite part was just getting my daughter into it and watching her walk around. The open back is very cute, very fun and great for hot days. It is a fun pattern for a slightly experienced beginners. The ruffle is a bit of work if you’ve never done one, but once you get it, you’ll be fine. The detail of the ruffle and versatility of this simple pattern is so much fun. My daughter LOVED this dress. She went outside on the slide and was able to even play it in.

    The cutting out process was very quick and simple, its usually the part I hate but I quite enjoyed this one. It’s something a little different to a simple A line dress, you will learn new techniques such as French seams and adding ruffles / bows so well worth a go.

    I loved the back of this pattern. The pattern was easy enough to put together and make. I recommend this pattern to anyone who is teaching themselves like myself.

The Small Print


Every pattern we make has been tried & tested first by our team, then by specially selected pre-testers, then by a group of up to 50 different sewers of different abilities, ages, sizes, shapes, body types, and experience levels.

We literally spend hours designing, testing and checking the pattern to make sure it works and the instructions are easy to follow. Hopefully you’ll love the end result as much as we do! But, if for any reason you don’t, please get in touch so we can help.


This pattern can be used to make beautiful little garments for personal use, or can be made in limited quantities to sell. You can only sell the finished product; you cannot sell the pattern or these instructions. We’d love you to include a credit to as the pattern designer when you make garments from the pattern to sell, but it’s up to you.


As soon as you have paid you will receive a link to download the pattern, so you can get started immediately if you like. Note, this is a digital, download-only pattern. You will not receive a physical copy in the post.
