I don't know German and here is the sentence.
"Wunderbar! Peter look! Wie die geht! Wie die aussieht, die ist genau meine Kragenweite!" (Arnold Wesker, Kitchen)
I used google translate but couldn't understand what he means. Previously he was talking to a waitress he likes at work and when she answers him, he says this to his friend peter. Is he talking about the way she works? How she looks? How a tie would fit him?
(Genau) jemandes Kragenweite sein is a German proverb meaning
to be to one's taste
to find something/someone likeable/appealing
or
to be with someone at the same level
Imagine a shirt collar that fits perfectly around your neck (collar size - Kragenweite).
A similar english proverb might be
suit sb (right) down to the ground
My cup of tea
In this case, the man is talking about a woman he sees, so you can translate it like this
"Wonderful! Peter look! The way she walks! The way she looks, she suits me right down to the ground.
Alternative:
she is exactly what I'm looking for
she is what I'm talking about
she is my cup of tea
edit:
From the comments:
she's just my type
