Pink Flamingo Costume - made this last Halloween. Mine turned out a little different because the link doesn't have any instructions so I had to figure things out on my own. I loved how it turned out though. So many compliments!
Isn't this scuba diver costume adorable? You could use Jalie pattern 3135 for the wetsuit: http://www.jalie.com/jalie3135-skinsuit-sewingpattern.html. With all the sizes included in the pattern, you could even make matching father and son costumes!
