The fabric choice was dark blue baby corduroy and some red/peach linen I had in my stash for the linings. The boy for whom the suit is being made, Darville, likes to wear suits as everyday wear, so it needed to be durable.
Darville measured as a 5/6 for height and chest measurements, but a 3T in his hips. I cut everything out as a size 6, to give him some growing room. I made the trousers up as normal, then took in a half inch off each side to get a better fit. The size 6 also has half elastic in the pants, for a flat front, compared to 3/4 elastic in the smaller sizes. To allow room for growth I put in 3/4 elastic here too.
The lining of the vest is in the red/peach linen, as are the welt pockets. The vest pattern doesn't have pockets on it, but the jacket does. I lined up the armscye of the cut out vest, and the armscye of the jacket front pattern piece to place the pockets. The vest pockets were important for the pocket watch he was also getting as a present. The pockets on the jacket were left off.
