I just wanted to show you my favorite boys pants pattern, and one of the best thing about it is that it is FREE. I found it on Dana's blog MADE.
They are so awesome that I have made heaps of them. Some with pockets, some with a lining , some with a flat front and some with the full elastic waist. I have made them for my boy and for my girl. The pattern suits both. The size of the pattern that you can print out is a 2-3 so that is perfect for my daughter and I just made it a little larger for my boy who fits size 4.
I have noticed that the waist is a little on the low side so for the last pair I made I adjusted the pattern for the waist to sit higher. It turned out that I allowed a little too much extra length that the pants were mega baggy in the crotch. So after I had just finished them I had to unpick the waist and fold it over one extra time. When completed they fit just fine and I am happy again :-)
My son chose the contrasting yellow cotton. I think it is a good combination.
Here are a couple of other pairs I also made.
