I should have known Yoga "pants" were involved. Also, "Cotton Flare" sounds like another term for Bell Bottoms.Technically, the first 2 pairs were yoga pants...
The 3rd pair is similar to what Goku Black wears (do not question my logic for buying them!)...
The 4th pair are called "cotton flare" pants...
and the 5th pair is, you guessed it, another pair of yoga pants.
