How would you describe Polish girl in one word only?

I don't think Mary Poppins is Polish; but you never know!

I believe the word supercalifragilisticexpialidocious describes Polish females very well.
According to Wikipedia; "The roots of the word have been defined as follows: super- "above", cali- "beauty", fragilistic- "delicate", expiali- "to atone", and docious- "educable", with the sum of these parts signifying roughly "Atoning for educability through delicate beauty."

edit: Besides, I believe her real name was Maria Poppinski

gentle

Friendly

spectacular!
