When planning a grouping of Alice in Wonderland themed costumes for my family, I had visions of dressing my 11-year-old niece, Claudia, as Alice. We’ve gotten lots of requests for sizing down Charm patterns for little kids, so this was the perfect time to experiment!  For more images, measurements, and details, be sure to see pages 20-22 of Issue 7 of Vintage by Gertie Magazine. 

Claudia lives far away, so we really had to wing it for this one. Here are a few tips we learned while creating her Alice costume:

Choose a Simple Pattern With Fewer Pattern Pieces Children aren’t shaped like small adults. They have different proportions, which means a fitted garment that uses an adult-sized pattern block won’t fit. Avoid patterns with significant shaping at the bust, or with details that emphasize a woman’s curves. For our Alice costume, we started with the Cinch-It Dress, a trapeze dress with a very loose fit, in the smallest size available (size 2, with an A-cup).

Get Out Your Calculator Sizing a pattern up or down requires a bit of math, and you’ll need a few extra measurements. Compare the body measurements to the size chart and the finished measurements listed in the instructions. The Cinch-It Dress has significant ease built into it, so we were most concerned with the fit at the shoulders. Compare the bust measurements between your model and the size chart. In our case, the pattern is 4 inches larger. To find the percentage difference, the math is as follows: (Model’s measurement x100)/ Desired measurement= percent difference. When we plugged in the Cinch-It Dress measurements and Claudia’s measurements, we got a percentage of about 87%, so we found we had to reduce the size 2A pattern pieces by 87%.

Print the Pattern Smaller and Correct the Seam Allowance Print out the pattern pieces using a printer with a custom scale setting set to 87% (or your desired percent difference). Check the test square: it should be .87 of an inch, or just a smidge smaller than 7/8 inch.

Measure your pattern pieces to make sure they will fit your model. The shoulder fit is especially important (for kids as well as adults!).

Before cutting out the pattern pieces, you’ll want to adjust the seam allowances. Our scaled down seam allowance measured just over 1/2 inch, so we added 1/8 inch to the cut line to get our usual 5/8 inch seam allowance. Of course, you could also just sew the garment using smaller seam allowances.

Test the Fit With a Muslin Don’t skip this step! Make a full muslin of the garment, including the collar, sleeves, cuffs, pockets, belt, or whatever other details are included in your pattern. Not only will this help you test the fit of the garment and determine the correct length, it’s also a great tool to make sure the placement and scale of the details are correct.

Complete the Costume The final Cinch-It Dress was sewn in blue cotton, with a white pinafore created by combining the Stanwyck ruffled bib (scaled down to Claudia’s size) with a simple gathered apron that tied at the back. White socks or tights, a pair of black patent shoes, and a black headband will complete the look— but I’ll let her mom worry about that!
