Romper Measurements

These measurements are simply what I came up with and can be used as a guideline for any size.  The example measurements are what I used for and 18 month romper.  Sorry that I know they aren't very technical and my drawings are how I visualize things for myself {on the back of old business cards ha}...I'm not really a seamstress:) 

Top:
Width of fabric = child's waist measurement + 3 inches divide by 2 (you will have one piece for the front and one for the back so you only need half the width for one piece)

Length of fabric = child's shoulder to crotch measurement + 2" x .6

Example: Width of fabric = Waist measurement 19" + 3" = 22" / 2 = 11" 
Length of fabric = Height from shoulder to crotch 16" + 2" = 18" x .6 = 10.8" round to 11"

One arm hole = I used a shirt and traced the arm hole
Shoulder = I did 2" wide, but you can do it as thick or thin as you want
Diagonal = Measure how far from the top the other arm hole is (ie 3.5"). Use a ruler to make a diagonal line from that point on the outside to the edge of the shoulder strap.  Make sure the diagonal does not go lower than the other arm hole.

Bottom:
Width of fabric = child's waist measurement + 10" divided by 2 (you will have one piece for the front and one for the back so you only need half the width for one piece)

Length of fabric = Height from shoulder to crotch - the length for the top + 4"

Example: Width of fabric = Waist measurement 19" + 10" = 29" / 2 = 14.5"
Length of fabric = 16" - 11" = 5" + 4" = 9"

Crotch = In the center of the bottom cut a horseshoe shape 1" wide by 1" high

Ruffle:
Decide how far down you want it to hang (I did mine 3 inches).
Double the length of the diagonal opening (ie 16" opening means 32" rectagle of fabric).
