how to make flared legs on longies?

[mkmb129]

The pattern says to make two stitches at the inseam.. but that has left only one side flared, and it looks silly, so I have to frog. Is there a better way? Splitting the stitches in half and make one stitch at each side seam maybe? Or is there a smoother, nicer looking way? TIA!

Maybe m1 at each side, inseam and outside 'seam.' Might need 2 increases on each side.
