This looks like a pattern I had from my sister (she's now 39). I used it for my daughters and godchild. Let me scan the pattern instructions and email it to you. Can you PM me your email address and I'll do it tonight?
Yes, i fought with the collar too. I also made it in the 6 months size and lengthened it for christening gowns (no collar). My godchild's was the nicest- layers of satin and lace and tiny roses I attached with long streaming satin ribbons. She was a bit slippery, but beautiful!
