You're probably knitting with the two 'back' needles so your knits are being done on the inside. Imagine that your work is a cup and you 'sip' from the side facing you. Those are the two needles that will result in the knit stitches being on the outside.
If you've worked the legs and the purl bumps are on the outside, flip them inside out so the V's are on the outside. Then use your circular needles, making sure that the tips are toward you and the cord is away from you. That will put the knits on the outside.
"Trust the pattern!"

Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
