Baby boy vintage suspender shorts, dark blue, fall - winter

Description

This item is a vintage suspender jon jon for a baby/ toddler boy.
It is made of dark blue fabric ( almost black) which feels like a wool blend. It has the sweetest embroidered  leaves on one side of the chest in dark red.
It has no size or manufacturer's label.
My best guess is that it will fit a baby wearing 12 - 18 months.
It measures as follows:
shoulder to crotch ( with buttons in current position): 19"
Buttons are at the ends of the straps  so the suit can be   shortened by moving the buttons up; it cannot be lengthened.
chest: 18"
waist: 19"
hips: 22"
It has nicely made straps,  back elastic, and a  tiny pocket on the back.
The fabric and embroidery are of very nice quality.
This piece is in excellent vintage condition. Its only flaw is some loosened stitching and wear on the edge of one leg, as shown in the last photo.
A very nice outfit for fall and winter, paired with a warm shirt and knee socks.
The shirt is a prop only and is not included in the listing.
