Wedding dress alterations before and after

This is the wedding dress I picked up at the thrift store. I really loved the puffy sleeves, but the dress needed some serious alterations.

Cutting a petticoat to wear under the dress

1. Cut the petticoat

I decided to put a petticoat under my wedding dress, but since it was long (and see-through), I had to cut it to a shorter length at the third layer. 

Wearing a petticoat under the wedding dress

This was the result - a better length to work with. I wanted to show the middle layer ruffles, but I was pretty indecisive about leaving the original length or taking it in. I decided to leave the dress as is. 

Pinning the side seams to take them in

2. Take in the side seams

Next, I pinned the sides as the dress was super loose and definitely needed to be taken in. Luckily, my dress already had side seams, so I won’t be losing the structure when taking it in. 

Taking in the side seams of the wedding dress

Here, I’m sewing the two layers in a straight line, following the pins as a guide. Turn the dress inside out so that the excess seam is on the inside. 

How to alter a wedding dress yourself

Here’s how it looks after. 

Changing the neckline of a wedding dress

3. Modify the neckline

I really wasn’t feeling the sweetheart neckline; I wanted a more squared-off vibe. So, I took a top with a straight neckline and traced it onto my dress using pins. 

Drawing a straight line with a ruler

Next, create a straight line with a ruler. 

Altering the wedding dress neckline

Because the neckline is pretty high, I also marked upward to the shoulder pieces. 

Cutting the neckline of a wedding dress

After gathering courage for this step, I cut the line and pinned the excess fabric. 

Changing a neckline from sweetheart to square

When doing modifications like this, it’s best to turn the dress right sides out to see your progress and what it will look like as you go.

Creating a deeper neckline on the dress

I wanted a deeper neckline, so I repeated the above process and cut into the fabric more. 


Once you’re satisfied, then go ahead and sew to secure! 


Tip: Iron down the fabric before sewing. 

Trimming the excess fabric

I cut off the excess fabric so the neckline would lie flat.

Gluing the neckline flat


Ruined neckline on the wedding dress

Changing the neckline of the wedding dress proved to be a little challenging, and you’ll soon see why. I used fabric glue to flatten the remaining panel of fabric from underneath.


After a day, I was left with a very uneven, blue-tinged neckline. I wanted an invisible seam, but I didn’t realize that blue chalk + liquid stitch + thin fabric was a recipe for disaster. 

Lace trim from a white blouse

So, on my second attempt, I cut out a lace trim from a beautiful white blouse that I had.

Hand-sewing the lace trim to the neckline

Next, I hand sewed it onto the neckline, and it actually turned out great!. 

Adding lace trim to the neckline of the dress

I started from the back of the left sleeve and worked my way to the back of the right sleeve. 

Measuring elastic around the shoulders

4. Add elastic to the sleeves

Now it’s time to add elastic to the sleeves so they hold better and more upright. For this step, measure the elastic around your shoulders, as shown. 

Pinning the elastic to the sleeve

Pin the elastic on the raw edge of the sleeve. The elastic is shorter than the length of the sleeve, so there will be a lovely ruffle effect, too. 

Folding the fabric over the elastic

Fold the outer raw edge over the elastic to create a tunnel and sew to secure. Feed the elastic through the tunnel afterward.

Sewing elastic into the sleeves of the dress

Once the elastic is in the tunnel, sew both ends to the fabric and close the gaps.
