Size Medium/Large (36-38'', 92-97 cm in bust circumference) .

Size 5 cotton thread, 49.6 г - 210 м, 1.75 oz - 230 yards, crochet hook 2 mm.
Gauge - square motif side is 16 cm.

Bottom (squares):
Make 6 squares wide and 4 squares high (upper left and upper right squares are partial.)

Connecting squares:
Connect squares as you go by p, but not by ch-12 sp at the corners.

Only when you have 3 squares,connected by p, make 4th square and make connection where 4 corners meet (instead of ch-12): ch 6, insert hook in 3 ch-12 sps of other 3 squares (counting them counterclockwise), yarn over (yo), draw yarn through 3 ch-12 spaces, [yo, draw yarn through 1 loop on hook] twice, ch 5.

Each front part is 1 3/4 squares wide, the rest is back.
Upper part of vest: crochet up from the bottom.

ROW 1 :
front: 62 dc, back 121 dc, front 62 dc = 245 st

ROW 2 (stars):
Right front part: work on 62 stitches.

5 stars for each side (1 partial) , 10 stars for the back = 20 stars

Start from the armpit.

Connect in every 6th dc.
The last star is missing one beam, to decrease. Connect 3rd beam of this last star by tr to the last dc.

ROW 3: Ch 5, instead of every 6th ch make 1 dc and connect 2 beams of neighboring stars at the same time = (55 stitches above 5 stars) plus ch 12 for a sleeve.

ROW 4: 67 dc
ROW 5: net: ch 5, sc in every 4th dc, except first sp (connect first sp in 2nd dc - to make smooth decrease) = 17 spaces.
ROW 6: ch-5 net, decrease 1/2 of ch-5 sp
ROW 7: ch-5 net, decrease 1/2 of ch-5 sp
ROW 8: dcs

ROW 9: 5 stars, connect last one at the neck line in 8th dc from the edge by tr.
ROW 10: ch sts
ROW 11: dcs
ROW 12: net, 1st ch-5 sp at the neck line in 3rd dc from the edge, the rest in every 4th.
ROW 13: ch-5 net, do not decrease
ROW 14: ch-5 net, do not decrease.
ROW 15: dcs
ROW 15: stars
ROW 16: dcs = 62
ROW 17: ch-5 net
ROW 18: ch-5 net 2/3 ( to make smooth shoulder)
ROW 19: ch-5 net 1/3

Left front part: the same as right.

Back:

121 dc.
Make 10 stars in first row,
Row 2: add ch 12 to every side (sleeves) = ch 145 (121 + 12+ 12) (connect with all stars while doing this row by dc instead of every 6th stitch)
Row 3: 145 dc . We need 61 dc for every shoulder + 46 for the neck hole = 170 dc. So, increase 25 sts from 4th to 16th rows at some points.
ROWS 4,5,6 - ch-5 net
ROW 7: dcs
ROW 8: 13 stars
ROW 9: ch sts
ROW 10: dcs
ROWS 11,12,13: ch-5 net
ROW 14: dcs
ROW 15: 14 stars
ROW 17: ch-5 net, connect with front shoulders while crocheting (I connected 5 arcs)
ROW 18: ch-5 net, connect with front next 5 arcs from the edge.
ROW 19: ch-5 net, connect the rest of shoulders.

Connect sleeves at the armpit by making a net somehow :)
Then make the edge around all edges of the vest. (I made *5 dc in one stitch, skip 3 ch sts, sc, sc, skip 3 ch*, repeat from * to *
