In the example I am shortening the pattern to ch-56 and not 166 as it does in the gown pattern to make it more manageable for me. I will note my changes in brackets: []. I am also omitting row 1 because it is a basic ch and then single crochet the length of chain which is something everyone should already know how to do.

ROW 2: Ch-1, sc 1st st[ch], (ch-5, sk 3 sts, sc next st) twice, * sk 1 st, 5 dc next st, sk 1 st, sc next st, (ch-5, sk 3 sts, sc next st) 3 times, rep from * 9[twice] times, sk 1 st, 5 dc next st, sk 1 st, sc next st, (ch-5, sk 3 sts, sc next st) twice, turn.
