girls collared shirt

I would like to make a shirt/blouse with a peter pan collar for my 6 year old. I can never find these shirts in stores in her size. They usually only sell them to 2 year olds, and the 6 year olds get styles which are too old for them, imo.
Does anybody have a good suggestion for a successful pattern for a low intermediate sewer?

Thanks!

This is a cute Oliver and S pattern.  It may be what you are looking for.

yes, I have seen that one. It is very cute. Unfortunately, it only goes to size 5 and I'm looking for a size 6. I'm not advanced enough to know how to enlarge a pattern. I can only follow directions...no creativity! Darn.

Thank you anyway.

I'm sorry...I didn't realize it didn't go up to the right size.  You could try searching on Etsy.  There are a lot of vintage patterns on there and a lot of them have peter pan collars.  This might be a way of finding a really great pattern that no one else has, too.
