As I mentioned, here is the first part of my tutorial on how to take in a dress shirt! At least, the methods and tricks that have worked for me the last few times I have taken in John’s shirts. I’ve separated this into two posts; this one on pinning and measuring, and the next on cutting and general tips.
Let’s start! You can kind of tell that I’ve pinned in the sides in the picture below, but I also added another to show where the pins are. I pin the shirt in while on the person of course, making sure to make it as even as possible from side to side. For the sleeves I taper from the elbow down to a point 3-4″ up from the cuff seam, since it is very difficult to get close to that seam with a sewing machine. Make sure to always put the pins in pointing to the floor – it’ll reduce the chance of the person wearing the shirt pricking themselves! The whole point of taking in a shirt is of course to make it slimmer, but keep an eye on draglines.
There is a limit to how much you can take in without distorting the fit, so I’d recommend not taking in much more than 4 inches total at the armpit / side seam intersection. If you need to take in more, you might want to think about reshaping the armscye and sleeve head (not covered here).
I find that the biggest job in taking in (or letting out) any garment is this next step of recording the points you’ve pinned, then averaging those numbers out. This is the same technique I used when working in the bridal shop, and in pretty much any setting where I need to let out or take in seams equally on both sides of a garment. It makes sure you get a smooth line from top to bottom, and of course – being the same on both sides!
- your pinned shirt
- pen and paper
- measuring tape or ruler
I start by measuring out every 2 inches (or every 5 cm if you think in metric) starting from the hem and working my way upwards. I mark each point by a pin perpendicular to the stitching line. When I get to the armpit I mark that seam with a pin even if it isn’t quite at the 2″ mark from the previous one. I start counting from zero at the armhole, moving towards the sleeve cuff. Repeat this for the other side.
Next I revisit all the 2″ marks and measure how far in the pins are from the original side seam. If the 2″ mark is between two pins, just eyeball it the best you can. Note down the distance for each point, first for one side and then the other. As you can see, I curiously marked points in 2-inch segments, but I measured from the side seam in centimeters! I find centimetres much more accurate for smaller distances, but whatever floats your boat works.
Now get in touch with your mathy side. Again, I find the next step easier to do in centimetres, mostly because I can so easily see where the midpoint between two numbers should be. For example, if I’ve measured a particular point on the left side to 2.4 cm and 2.8 cm on the other side, I average it out to 2.6 cm.
I average out each point individually first, and then I work my way down and make sure my new line won’t resemble a zig-zag, darting in and out. You can maybe make out in the picture above that I changed the average number for the 8″ mark from 1.9 cm to 2.0 cm. Looking at the big picture I can tell that the amount taken in increases steadily from the hem to the armpit, and then back down, so it makes no sense to dip down at the 8″ mark when the big picture tells me otherwise. So I changed it! This is the time to smooth out all these lines, and to trust your eye, your gut and your experience.
The process is pretty much the same for the darts I took in. The darts are more freestanding in the middle of the shirt back piece, so you’ll have to get some important measurements recorded and evened out. They include how far up from the hem you start the dart, the length of the dart, the deepest point of the dart, and the distance from the side seam to the bottom of the dart. You can see my drawing in the picture below. As with the side seams, I measured out 2″ distances, recorded the pinned in amount at those points, then figured out the averages.
That’s it for today! And quite honestly, it’s the part requiring the most concentration, and is the groundwork for everything coming after. The hard part is now done! I’ll have the next post on cutting, sewing and general tips up later in the week.
