When you are buying vintage patterns, please refer to the actual measurements and not the size number on the pattern envelope. Vintage sizes, especially pattern sizes, are very different from today's. Please keep in mind that patterns can be adapted to fit a range of sizes and you can find tutorials online that show you how to do it!
