I typically wear size 12 or 14 in Originals & Easton dungas. 5'2", 92-94" waist.
First pair of Mullen in green, I ordered 12, and it was huge - like 5 inches ease at the waist, which is ridiculous! This time, chose Red Hickory stripe in size 10 for a snugger fit, which is...OK.
Mullen has 2 buttons on the side, with a smaller, shallower pocket than Easton (which has 3 buttons on the side). The front bib pocket on Mullen is wider, with stitching in the middle, but that means it's not wide enough to hold most phones. The hip is cut fuller than Easton, and the legs seem wider/ straighter than Easton cut, which is a bit more tapered. I wish the photo on the site would show the back view. The belt loops are definitely useful for this cut, as I deff needed to belt the size 12.
Seriously, the side loop is silly. Most workwear places a side loop above a side pocket to anchor longer tools that you place in the pocket. I suppose you could place a wide-headed hammer in the loop...but meh. The shallow hip pockets make this style less suitable for workwear than Easton.
Overall, I think the Easton cut is more flattering at the waist and hip. I prefer it to Mullen, which has a boxier fit. My preference is to keep purchasing the Easton dungas, so L&Y, please don't discontinue them!!
