Nothing says Summer quite like crisp white and bright navy blue. Pair those colors with an easy-wearing, dress-length tunic, and it is a recipe for comfort and versatility.
This is one of those projects which took a couple of years to evolve. I purchased the white polka-dotted cotton voile from Britex Fabrics about two years ago, thinking I would make a blouse. I considered patterns for it every once in a while, and then put it back in the cupboard. What was keeping me from moving forward on it was the fact I had over 2 yards of this 56” wide fabric, more than enough for a blouse. Using it for a dress seemed the more efficient way to proceed. All I needed was some inspiration.
Then last Fall, I purchased a copy of the then-newly-released The Tunic Bible by Sarah Gunn and Julie Starr.
Well, there is lots of inspiration in this book, and I especially was drawn to this style, but in a dress length.

Shown on page 65 in The Tunic Bible is this top. The combination of the wide split placket, the angled collar, and the split cuffs really appealed to me. All three are really lovely details. (I purchased my copy of this book on Amazon.)
(Now here’s a bit of trivia: a tunic dress is not the same as a dress-length tunic, according to the number one definition in Fairchild’s Dictionary of Fashion. A tunic dress is “a two-piece dress with a long overblouse worn over a separate narrow skirt,” although the definition was expanded a bit in the 1960s to cover a tunic mini-dress.)

Back to my dress: I knew I wanted to embellish it with Petersham ribbon (which is so malleable and cooperative!) In choosing a color, I went for bright navy blue, also ordered from Britex Fabrics.
I actually have three tunic patterns in my collection, one just a couple of years old which I have used, one from the 1980s (also used), and this vintage one, not used yet:

The description on the envelope does not describe this as a dress length tunic, rather an “A-line dress with a caftan neckline.” But, of course, it has a tunic look.
But I decided to give the pattern included in The Tunic Bible a go. I transferred my size to pattern tracing paper and made my muslin. I knew I would have to line the main body of the dress (the fabric is translucent.) After considering two types of light-weight white linen, which I deemed not quite opaque enough, I went with white muslin.
The first thing I did was make the stand collar, so that I could see how the blue Petersham ribbon would look; I was a little worried that the intensity of the blue color might be too much for the delicate white fabric, but I was pleasantly rewarded with a look I liked:
I used Dritz Wash-Away Wonder Tape to make the application of the ribbon precise. This was the first time I have used this product, and I thought it was wonderful! I haven’t washed my dress yet, but supposedly the Wonder Tape washes away without leaving a residue.
It is especially important to follow the sequence of construction when it comes to the front of the dress, as the neckline trim needs to be applied even before the bust darts are sewn. Once I had the front and back of the dress together, I decided it was a little too baggy (this did not show up in my fitting muslin, which sometimes happens…) So, I added tapered darts to the front, which was an excellent solution.
Applying the trim to the hemlines required four mitered corners. One way to help get a precise corner is to use a straightedge to guide the miter. Here you can see I used the end of one of my little slide rulers which was the perfect width:
One of the things I love about this color combination is its versatility. In these photos I have paired it with turquoise, but it looks equally good with accessories in orange, red, yellow, green, and of course, blue.

The darts I added to the front give the dress a nice fit. I also used a 12″ side zipper, or else I would not be able to get the dress on!

Here I have the split cuffs hanging down. I think I prefer them folded back, as shown in all the other photos. However, it’s nice to have the option of wearing them either way.
I suspect there will be a couple more tunics to sew in my summers to come. If there will be in YOURS, I would definitely recommend picking up a copy of this book, if only for the abundance of photos and style options which are handsomely presented. I do recommend that you familiarize yourself with the layout of the book before starting your project. The layout is logical once you understand the formula, but it’s best to give the book a thorough study before you proceed.
And now, with my sights on Fall and Winter (I can’t believe I am saying that!), I think this will be the last of my sewing for Summer. However, I should end with this MEMO to family and friends: Expect to see me in this dress often over the next six/seven weeks. It is Tunic Time, indeed!
