Do your fave jeans that you have had for many years not fit you now? Are they soo baggy that you have to wear a sweater so they do not fall? 🙋. Yup, I have been there too. Lets get to mending!


Jeans vary in size and types. Mine is a boyfriend jean, I began wondering are they obviously called boyfriend jeans because they are modeled by your boyfriends jeans? Sorta, they are actually modeled after the first blue jeans in 1873, with a feeling of chilled relax vibe like a boys jeans. This does not mean necessarily that boys jeans are all baggy and relax. Share in the comments, what type of jeans you are mending 😃   


Denim is one of the best fabric to mend. Plus as the years past by the fabric gets better. Wanna learn more about denim? Here is a nice brief of its history, check it out 


The grading of the stitch I used was 3. It can vary based on your sewing machine.

After I made the dart, I tried on the pants to see if the dart would bother me and it does not. So I left it intact. If you feel that the thickness of the dart will bother you, you can cut open the dart, iron it down and zig-zag the edges of the seam. 

Keep in mind, that if you cut open the dart and if you ever want to make it bigger instead of smaller in the future, you will need to patch the gap. 


The more aligned your lines look, the less visible your alteration will be.  The alteration will be neat and seamless. Exactly as we want it to be!


I hope you find this tutorial....easy, gentle & great! (btw, we made the abbreviation egg ahaha)


Downsize Your Jean Waist

Prep time:2 mins | Make time: 30 min | Total time: 32 mins

No one will notice you altered your jeans!


  • Jeans
  • Ruler
  • Seam Ripper
  • Chalk Pencil
  • Fabric Scissors
  • Sewing Machine
  • Matching thread


  1. Wear your jeans inside out.
  2. Pitch the center seam in the back of your pants to determine the amount you need to take in. As you hold the pitch of fabric, draw a line against both sides of the extra fabric.*
  3. Place your jeans on top of the cutting mat and with your ruler and chalk pencil straighten the two lines into a dart.
  4. Use the seam ripper to remove the belt loop and then the seams of the waistband. Do not seam rip the entire waistband, just about 1 to 2 inches away from the chalk line. Be super careful, have the hand that is holding your fabric away from the area you are seam ripping.*
  5. Draw a center line in the middle of the loose waistband, then snip. Caution: You are cutting the loose waistband not the pants.
  6. Grab two pins to pin down each side of the waistband. Fold the dart you made and pin. You can use two pins, the most important thing, is that the dart folds well.
  7. Sew the dart with a straight stitch. Make sure to remove your pin as you sew. Tip: As you reach the end of your dart, sew straight up. *** OPTION: 7a. If you feel that thee thickness of the dart will bother you, you can cut open the dart, iron it down and zig-zag the edges of the seam.
  8. Remove the pins holding down the folded waistband. Choose one side to snip .25" and the other you will fold the edges in. Next iron the folds 
  9. Sew the upper stitches. You are following the line where the previous stitches where. Then
  10. Pin the belt loop and sew in place using a straight stitch. 
  11. Enjoy!!


  • * If you can have someone to draw the line for you, that would be best. The help can make drawing the line easier and more accurate. 
  • **The grading of the stitch I used was 3. It can vary based on your sewing machine. 
  • ***By doing this, the dart will be flatten.
