Maybe since I've been a big fan of Annie Hall, houndstooth tailoring pants are
listed on my all-time favorites.
With a waistcoat just like Queen Annie, or maybe a fluffy blouse with a
feminine details can go with them very well. Or how about pairing them with
a striped top doubling patterns together?
And don't forget nothing like a contrastively colored belt can mediate between the talkative parties.
Colored belts always do me great job!
