Patterns

I bought this pattern at a local thrift store today. It had not been cut into and had the original instructions included. The pattern is a size 14 ( just my size). I thought about making the longer version but it is for a size 34 bust. I haven't been that in a long time. I don't know if it can be adjusted to a bigger size. I hate to take apart the pattern and find I cant make it fit. I remember wanting a robe like this a long time ago.
