In a few decades we have grown larger and, unfortunately, bigger, so manufacturers have changed the standard sizes of clothing.
A criterion has not yet been taken into account: women have an arched back!! Result, often pants have a back gap.
No need to be a great seamstress, it’s an easy fixing.
You need: 2 flat and thick buttons – some buttonhole elastic – sewing thread – a needle – 2 pins – a seam ripper – a thimble (for the more clumsy )
A pencil line would delimit as well, but the advantage of the pins is that they stop the seam ripper. No risk of going too far.
Sew the button.
Do the same steps on the other side of the belt.
Attach both ends of the elastic to the buttons.
The more forward you make the buttonhole, the more you will have a bloomer effect.
This technique is also ideal for large and lean children or for those who have a little tummy can. For many years, all of my children’s pants have been retouched.
