This is by far one of the most exciting and rewarding designs I have created thus far. This crochet Mermaid Outfit Pattern has taken me over a year to perfect, and due to popular demand, I am finally ready to share it with the world! I have added as much detail as possible and lots of photos to help you along in creating this gorgeous set, however, this pattern's difficulty level is hard and is not meant for a novice crocheter. This finished product will fit a baby from size Newborn to 3 Months.

This 15 page PDF (two files!) includes:
~A printable pattern
~Supplies list
~List of abbreviations and stitches used
~Over 20 progress photos for visual aid

Expect to use at least 7oz, or 250 yards of yarn to complete this project.

Extra supplies:
~3/8in elastic to make the waistband stretchy.
~Elastic for top and headband
~Decorative buttons (optional)

Finished Measurements of the Tail:
Length from waistband to bottom of tail: 20”
Width of widest part of tail: 8”
Waistband before stretch: 14” (will stretch to 20”)
Circumference of Tiara: 13” (with lots of stretch)
Circumference of Top: 14” (with lots of stretch)

The pattern was well written, I altered some things because I didn’t like the look of the bands so I just single crocheted around it. But other than that, it worked up very quickly.
