What does &P.I.R.& stand for?
You can go male or female hose threads to either 1/2 or 3/4 pipe thread or glue on.
Mostly summer clothes. Just remember that the baby will be comfortable in whatever clothes you'll be comfortable in at the same time. There's no telling how fast your baby will grow or how cold/warm it will actually be next year. Buy newborn clothes second-hand, at garage sales, goodwill, etc, to keep from spending a mint on clothes that she'll just grow out of in three weeks.
