Often, my customers will tell me to just stitch across the strap and cut off the excess.
Yes, you can do a version of that, but it seldom looks professional.
Many times, that procedure won’t work because when you pin it up, the front strap is narrower than the back strap. (We’ll cover what to do about that problem at the end of this post.)
If you want to know how to shorten spaghetti straps, look at this post.
But, if you’re taking up wider shoulder straps, stay right here because this is the place to be.
Here’s an example of a wedding dress that I got in this week where the straps are too long:
The customer tried the dress on and I just pulled up the straps and pinned them where the customer wanted.
This made the dress fit 100 times better.
You can see the closeup of where I put the pin in on one shoulder:
If you turn the strap over, you’ll see that this dress has lining and understitching:
You could take some of the understitching out now, or you can turn the strap inside out and remove the stitches that way.
It’s up to you.
I reached up into the dress between the dress fabric and the lining and pulled the strap inside out:
You can see the seam in the above photo.
Then I flipped the strap over and you can see the lining seam:
So, we have to take out a portion of the side seams here so that we can take up these two seams.
On the left strap, I needed to take up 1 1/4″.
So, I removed more than the 1 1/4″ needed. I ripped out about 2 1/2″ of stitches on each side of the shoulder seam:
Since I hadn’t removed the understitching before, I will do it now.
You should see two rows of stitching and I am removing both of those rows with my seam ripper.
The understitching is the stitching that is closest to the cut edge, so I take a little more of that out so that I don’t have puckers when I resew the seam later.
I remove the stitches on both sides of that strap.
Once that is finished, you can see inside where the rest of the strap is:
The only reason I am showing you this scene is that you won’t want to catch that inner fabric when we go to sew it up later.
But right now, we are going to take up the 1 1/4″ at the shoulder seam.
To do that, get out your seam gauge if you have one.
Measure the amount you need from the shoulder seam down.
In my case, it’s the 1 1/4″:
Stick a pin at that point.
Now, I want to match up the two layers. My goal here is to make sure the upper layer matches the lower layer.
On most fabrics this is easy because you can see the old pin holes:
Once that pin point is in the right place, I go ahead and finish pinning:
Do that process again on the other side of the strap.
In the photo above, do you see the spot where the pin first went into the fabric?
That is where I’ll begin my stitching. Actually, I begin on the edge of the fabric, but I sew right where the pin entered the fabric.
Some people would rather draw a line from one pin to the other.
I have been doing this so long that I can just “eyeball” the seam I need to make:
See how I am stitching from the entrance of the first pin to the entrance of the second?
Now this seam is parallel to the original seam:
Sometimes that is not the case. It would not be the case if you needed to take up more fabric on the arm side of the strap in comparison to the neck side of the strap, since many people’s shoulders are not straight across.
Once your seam is stitched, trim off the excess.
Since my fabric unravels, just by looking at it, I didn’t trim as closely as the manufacturer did when they constructed the gown.
I trimmed it off at about 5/8″:
Now, you’re going to repeat the process with the lining seam.
Again, take your seam gauge and measure 1 1/4″ down from the lining shoulder seam and stick a pin there:
Then, be sure to match the upper layer to the lower layer at the side seams and pin the fabric accordingly, just like you did with the main fabric.
Next, stitch across the strap being careful not to catch unwanted fabric underneath:
Trim the seam:
Now, you are going to stitch up the side seams following the original seamline.
It may be easier to show you what I mean with this drawing:
Make sure the shoulder seam is open flat.
Then, stitch your side seams like it is shown in red in the drawing.
Here is what it actually looked like as I was sewing:
(Note: you could stitch one side seam and then understitch that side of the strap, but I find it almost impossible to get my machine in that tiny opening and it’s hardly ever needed. A good pressing of the strap usually makes the strap lay down well.)
Now, turn your strap right side out:
Here is what it looks when I flip it over and you see the lining:
Press your straps if needed.
That’s it, unless you have straps that don’t match up when you first pin the dress or top for the alteration.
In that case, if the edges do not line up, follow the instructions above until you get to the part where you sew up the side seams of the strap.
Your straps will probably look like this:
You’ll stitch your new side seam along the red lines like this:
Then trim off any excess fabric and turn the straps right side out.
That should take care of the problem and make your straps look great!
In a later post, we’ll cover how to shorten spaghetti straps.
Until then, go shorten those wider straps!
