I have knit a bikini before, but it wasn't for me lol!! Actually it wasn't for a HUMAN at all!! It was for a manaquin!
She seemed to like it lol!!
Here's my proof:
I got the Pattern out of SNB book and the pattern was super easy, but, my only probem was "Roxanne" (that's the manaquin's name) lived 2 1/2 hours away from me and my step-mom kinda guessed on her measurments. I really should of made her top bigger. The bottoms worked good though. They fit me lol!! I heard that you can sew a pair of undies into the bottoms and that will help them stay on. Good LUCK!!!
