The Great Pattern Review
Nevtex
#7360 - Unitard
Denisen Hartlove - Highly Recommended
This pattern for a unitard is extremely simple and goes together without a hitch. I made a beautiful unitard in under an hour with only 4 pattern pieces needed (and that's including sleeves and facings). Note that the yardage and measurements are in metric numbers (this is a European pattern), so have a calculator handy.
