I've used voile for blankets, garment linings, even soft shoes... but I had never made an entire dress out of voile.
I think the main reason was probably because it's quite sheer. I would not recommend sewing an unlined dress in this material. You would definitely be able to see through it.
But for a lined dress, it really is fabulous, especially for those of us living in warmer climates like myself. Two layers of voile are still light, airy and just right, even for the hottest days.
Voile does seem to fray more than quilting cotton, in my experience. So, I was careful not to trim too close to the stitching. When clipping and notching curves, I left a generous 1/8"-1/4" of fabric between each notch and my seam.
I once had a double gauze dress that was near and dear to my heart fray through the seam because I clipped too close (but not into) the seam. I learned that lesson the hard way!
This dress does run a little big, especially on top. The fit of the top of this dress is quite generous in my opinion (but we are a small framed family). After experimenting to get the fit just right on Indigo's version, I decided to cut Evie's dress in a size 3 even though she normally wears a size 4. Then I added an inch to the length. Because of the slipperiness of the voile, it slipped off of her shoulder at times!
She has some growing to do before this dress will fit her perfectly. If I were to make it again, I would cut the top even smaller and then add some extra length to the bottom.
Evie told me she would only let me take her picture today if she could wear her hair down with a headband and hold flowers from our vase. She's a girl who likes to do things on her terms and this time I was happy to oblige. I love when it works out like that!
