Finished it this morning. A nice and easy pattern.
It is crocheted in one piece, starting from the lower part of the back.
Photo 2: here another one in 100% cotton.
Here another link to the schema and other examples of this vest:

Afhankelijk van het gebruikte garen, moet je wel voortdurend de maten met het schema confronteren.
Nummer 2 met katoen garen begonnen.

I started a knitted version (to construct).

Here another version in garter stitch:

And on photo 3 my own version in stockinette stitch. But I like the crochet and the garter version more!

Photo 4: another crocheted version in an italian 100 % merino wool.

Photo 5: same measures of the vest, here in cotton, but made following this last model here:
http://www.ravelry.com/projects/mmeera4/babyvestje-maat-56, only with hdc.

Photo 6: a vest with only hdc and a sample of the same model for Barbie, but closed with a string..

On photo 10 (white + blue vest) my first trial to modify the pattern a little.

May 2018: Photo 1: 2 further cardigans for Liberia.
June 2018: the 3 green-yellow-white cardigans are made with the wool Alize Real 40 (40% wool + 60% acrylic). Best result with hook 4,5 and 29 + 2 stitches casted on. A very soft wool!
JUNE 2018: other 2 sets, in red mixed yarn and green-yellow-white of Alize Real40.
December 2019: further cardigans.
4th of May 2020: another cardigan.
