I wasn't certain what you meant by swagger in this context.

Dictionary.com tells us: 1870–75; < Italian < Sicilian: orig., elegance, bravura, courage

So swagger would seem to be an appropriate translation.

Interesting, in the local language of the Italian region I was born (not Sicily), 'mafiosu' is used as a compliment for someone dressed elegantly. I always thought it was odd, but now it makes sense.
