Launching today is the first post in our Bootstrap sew-along for the month of February. A reminder, we have three garments we’re making: a semi-fitted women’s blouse, a classic trouser, and a jacket with diagonal zipper. These garments were selected as being classic, yet having opportunity for many possible variations.
Today, I will be leading you through the semi-fitted women’s blouse. This is a rather slim-fit menswear-style top with gently-shaped side seams:
This garment is probably the middle-ground of the three we’re featuring this month. Menswear shirt construction can be quick-and-dirty, or far more exacting when it comes to seam finishes. This sew-along will lean to the latter, but I will give you shortcut tips.
OK – let’s get started!
For the true, absolute beginner – let me talk about the parts of the shirt, as we see them on the Bootstrap pattern sheet:
From top left: under collar, upper collar, back body, patch pocket, and front. The front is formed with a double fold placket. Some shirts will have a facing – either cut-on or separate – for the leading edge.
At bottom, from left: sleeve (including a fitted, 3/4 length), collar stand, cuff, and back yoke.
Shirt patterns may or may not include yokes, and the yokes could affix anywhere on the front and back of the shirt; this yoke is dropped to the front of the shirt slightly (shoulder lines are marked on the yoke pattern, about 1 1/4″ from the yoke edge). Collars can be made a variety of ways, but this is more or less standard: a slight difference between under and upper collar, to make a good-looking roll line, and a separate stand. This is a very fitted sleeve through the shoulder – in general, you can tell by the very high, narrow sleeve cap.
If you have any questions about shirt parts – post them in the comments!
I am using a very lovely cotton suiting from Mood Fabrics. This was listed as a “suiting” but I believe this may be an error as it is very light-weight, and fine like shirting. In any case, there is a 3/8″ stripe that is subtle, but important enough to stripe-match. To that end, I made sure to fold right on a stripe, to cut the shirt front and back (next two photos):
Before cutting, note that I am going to be adding 1/4″ seam allowance to the armscye (for the yoke, sleeve, and front and back) so that I can French seam. If you plan on serging, or stitching and pinking, or a simple seam finish, you can keep the seam allowance at 3/8″. I do not recommend trying to French or flat-fell the seam without adding additional width, as the shoulder fit is a close one.
So, for most the marks on the raw edge, we can clip 1/8″ into the seam allowance:
I used a thread-tack to place the pocket edge. As I am cutting the shirt precisely on-grain, and the pockets are placed precisely on the crossgrain, I only need to mark one corner of the pocket placement. You will notice my perforated marks – I have made this shirt a few times now!
And ah – the sleeve! I find it helpful to label the parts of the sleeve. It’s simply two easy to get confused otherwise. I also put a safety pin on the front, right side of the sleeve. This has saved me lots of time and headaches. Note also below, my added seam allowance for French seaming.
I cut one yoke from the shirting, and the other from a grey chambray (shown beneath the outer yoke). This is the only contrast fabric in this shirt:
And the entirety of the cuff will be interfaced. Again, I cut a slightly larger double layer, and block-fuse. Block-fusing isn’t generally effective for larger garment pieces, but for these shirting elements it will do:
Finally, I interface two pieces for the placket. I have sewn up many, many shirt sleeve plackets (here is one method); you can use the pieces provided in the pattern, or one you find elsewhere. My method will be using a one-piece placket; if you want to use a two-piece method, simply cut up from the triangular slash point, after you’ve block fused:
The fused, then cut collarstand. Go ahead and mark your buttonhole placement (in blue carbon, at left) and your button placement (goldenrod thread). You don’t need to worry about which side is which, for now, as the collarstand pieces are identical:
The fused collar; mark “upper” and “under” in the seam allowance, to keep them straight later:
Marked: the leading edge of the buttonhole placement, on the fused cuffs (note crossgrain placement). Mark in mirrored fashion, on the right side of the two cuffs:
Go ahead and press the placket in a double fold as marked on the pattern piece. You can place the placket fold on the public or inner side of the garment; I chose the public side. Topstitch:
Mark your pocket reinforcement triangles with chalk, as a stitching guide. You don’t need pocket reinforcement but if there’s any chance these pockets will be used, it is wise:
Pin the pocket (aligning side of pocket to grainline, and corner of pocket to thread-marked pocket position, and pin:
Time for the yokes! You can certainly sew both the outer and inner yoke to the shirt bakc at once, but I like to sew them separately. Here, I am affixing the outer yoke to the shirt back, right sides together, right on the seam allowance:
I stitch right on top of the previous seam:
… and then grade it. (We are in for LOTS of grading, people!) In general, you leave the seam allowance closest to the public side of the garment, as the longest seam allowance. Grade, then press the seam up:
How, it’s time to create our finished shoulder seam! We are using the burrito method, which can be a bit confusing at first but it very simple (and is detailed on may blogs).
Set the shirt body aside. It’s time to mess with that pesky shirt placket! I am following a method almost identical to that so wonderfully illustrated on Pam Erny’s shirtmaking blog.
Most of the placket fuss, is making sure you set it up right. You will place the placket RIGHT side to the WRONG side of the sleeve, with he short placket piece towards the back part of the sleeve. The larger volume of the placket piece, is associated with the larger sleeve volume (if the placket line was cutting the sleeve in two):
Now, go ahead and mark with chalk, for reference to the top of the seam you just stitched. We are about to form the placket underlap:
Press the placket underlap seam allowance to the wrong-side of the underlap piece. Either finger- or steam-press:
Stitch from the right-side, 1/16″ away from this fold and just two or three stitches past your marked line:
Here is this seam, from the inside of the sleeve. Lovely!
Okay – time to tackle the overlap! We will be taking our long raw edge (at bottom right in the photo below) and folding it and pressing it at 1/4″:
Steam- or finger-press the overlap-sleeve seam allowance to the wrong-side of the overlap piece; fold the raw edge fold to enclose that seam, and press:
Go ahead and fold or shape your overlap head any way you like! I enjoy a classic triangle:
And – as per many awesome tailors before me, including David Page Coffin – I use a nice goupy bit of glue stick to really cement that triangle tip to the shirt. I usually set my sleeves aside to dry, and fiddle with something else for a while.
You can either stitch your overlap head down right along that previously-marked chalk line (as the aforementioned Pam Erny’s blog illustrates), or you can mark a parallel line a little further downstream. Just make sure both sleeves have the same markings:
To stitch, I start at the “closed” side of the assembly, stitch along this line, and pivot and turn to complete the “P” shape we end up with:
Time for the armscye! Remember, I added 1/4″ for a 5/8″ seam allowance, and I will be french seaming here. If you want a different finish, post in the comments and I can lead you through it.
Stitch the armscyes at that scant 3/8″ at about a 2 mm stitch (I lift my IDT and stitch with the sleeve head down, and the shirt body facing up). Using a tailor’s ham, press this seam open:
Now, trim the seams down to 1/8″. You will not want to catch any threads from the raw edge, in your second seam. And yes, it sucks to trim the two seam allowances separately, but it’s better to press open first, than to trim and then press open:
Now, it’s time to make up our side seams! We will French seam these as well, but I’m going to show you a little cheater method. Because the side seams are practically straight, we can make use of a serger (if we have one) to trim our first pass.
Perfect! Faster than trimming by hand, and no pesky threads.
Go ahead and fold the seam back on itself:
And stitch this seam! Make sure to pin well at the armpit, and sew slowly over this join.
This is the result you get from careful pinning – as you can see above I do not remove my pin until right before the needle traverses the intersection.
Go ahead and lightly press these side seams.
Now it’s time for that collar!
We are applying the outer stand first, then forming the collar, and then applying the inner stand – much like this well-photographed method by Andrea at Four Square Walls. This is when you need to think about which stand piece you will apply, depending on whether or not you want buttons on the right or left. This client I am sewing for (my oldest child!) identifies as non-binary, so I elected a masculine-style shirt with the buttonholes on the right. But don’t worry too much if you use the wrong stand piece – you can remark you buttonhole and button positions.
So first, pin the long raw edge of the stand, to the right-side of the neckline:
Go ahead and grade and trim your collar points (if you are a point purist or want to be, DPC wrote a wonderful article on this subject last summer):
