The first dress I have ever been proud to wear

Every dress I made before this had something slightly off. This one came out right. Wearing it to a family barbecue and having my aunt ask where I bought it was the best feeling I have had from sewing so far.

Maeve H.
The back zip was tricky at first

I installed the back zip three times before it sat straight. The instructions cover zip insertion but I think a tip about pinning from the bottom up would have helped me. Once I figured that out the third attempt went in perfectly.

C
Colette C.
More dress for less than any shop equivalent

A dress this quality in a shop would cost considerably more than the pattern plus the fabric I used. The finish is better too because I used French seams throughout. I cannot justify buying dresses in shops anymore.

Dalena Y.
Learned how to attach a full skirt to a bodice neatly

I had always had trouble with waist seams on full skirts because the gathers never distribute evenly. The instructions here give specific marking and basting steps that helped me keep the gathers even before sewing. My waist seam is cleaner than any I have done before.

Already have a winter version cut

My summer version is in a light cotton. I have a heavier cotton canvas in dark green cut and ready for a winter version to wear with a roll neck underneath. The pattern translates across seasons better than I expected.

How do I figure out the right size?
Before selecting a pattern size, take accurate measurements of your bust, waist, and hips. Choose the size from our chart that closely aligns with your measurements. 
If your bust/waist/hip measurements align with different sizes, you would want to choose the size based on the apparel category or the garment fit and make adjustments to blend sizes. For example, prefer the size based on your bust measurement for making a top, and waist measurement for a relaxed dress cinched at the waist. 
If your measurements fall between sizes, consider the fit you prefer (looser or tighter) and the type of fabric you'll use, as some fabrics have more give. All patterns include finished garment measurements which can be helpful to know how much ease or extra room is built into the design.
