Sorry my pics are so big ! I made my 5 year old DD some jeans out of a old pair of mine. They had holes in the crotch and no the back pockets lol.
There is a sewalong for this at Sewingmamas Forums so Credit to the OP there.
I took a pant pattern in my daughters size, lined them up on my jean legs, cut it out , sewed the crotch up and then made a casing for a elastic waistband, inserted elastic ,stitched up back. Added ribbon trim of her choice and a matching tank and this is what we have.
I didnt have to do ANY side seams or hems since they were already done on the jeans. This was a pair of flare legs I had.
Enjoy! Kat *mom of Valarie-Michelle The cutie poser here !*
