@AskEmmi - Wearing A Shirt Untucked?

Q: How do I know if I should wear a button-down shirt tucked or untucked?

A: Length and fit will determine that.  Below is an example of the right length for an untucked shirt.  What you want is for the shirt to hit you no more than an inch below your hip crease.  Proportionally, up to an inch and a half higher than the photo is good too but no lower or your legs will appear shorter than they are.

Perfect tuckout

Also notice that the shirt's fit is lean, also known as tailored, sport or European cut.  Traditional or American cut shirts that fit looser around the torso should really be tucked in.
