People try on their first pair of baggy jeans and panic. The legs feel enormous, the seat has room to spare, and the instinct is to swap for a size down. Hold on. That volume is the product. You paid for it.
A baggy pair fits when the waistband sits where you want it and stays there without a belt doing all the work. That is the whole test. The thigh, knee and hem are cut wide by design, so judging them the way you would judge straight jeans tells you nothing.
Our fits use alpha sizing, S through 3XL on most pairs. Take the size that matches your waist in inches on the chart in each listing. Between sizes? Go smaller. The cut already gives you more room than a size up would on a regular pair.
Wide legs are meant to reach the shoe and fold. One or two stacks of fabric on the laces reads right. If the hem hovers above the ankle, the silhouette collapses into something that looks accidental.
Most of our inseams run long for this reason. If you are under about 5'7", expect to cuff once or take the hem up an inch, and no more than that.
Too big: the waistband gaps at the back, the crotch hangs near mid-thigh, and the pair slides down within an hour of wear. Too small: the waistband digs when you sit, and the fabric pulls flat across the thigh instead of draping. Note that a draping leg with a comfortable waist is not on this list. That is the fit working.
Barrel legs taper back in at the ankle, so the hem stacks less and the curve at the thigh does the talking. Same waist rule applies. If you want the full breakdown, the barrel guide next door covers it.
