What's the difference between straight pants, feet pants and pencil pants?

The main difference between these two kinds of trousers is the cut from calf to trouser leg.

Straight pants are cut into rectangles and equilateral from knee joint to ankle joint, and they are loose to wear. Judgment method: You can fold the trouser leg in half to the knee joint of the trousers, and the width of the knee joint is equal to the width of the trouser leg, which is straight trousers.

Feet pants are similar to pencil pants, and the cutting form is mainly small legs, which taper inward from crotch to toe, highlighting the leg shape when wearing.
