I know there are several threads about AG jeans, but they are at least a couple of years old so I'd rather not bump them. That said, I'd like to contribute my recommendation for the Matchbox, especially for people with larger legs who struggle with finding slim-straight jeans that fit both their waists and thighs, and still taper to a good fit in the calves and leg openings.
First off, my dimensions: I wear size 32 waist, 34 inseam (probably literally 33 but I like the extra inch). My thighs are 23 inches in diameter, and my calves are 13 inches.
I have struggled with finding slim-straight jeans that fit my waist and thighs. I've tried APC New Standards, Naked and Famous, and several other brands recommended on these forums. Some might fit my waist and thighs, but the leg opening is too wide and floppy. One good brand I found was Nudie Slim Jims, which are great, high quality jeans, but until just recently, after 8 months of wear, the thigh and calf fits seemed a bit disproportionate to each other. The thighs fit fine but the leg openings were slightly too wide. Now they fit great, but that is due to some slight thigh stretching that makes them fit a bit closer to straight cut. It makes it difficult living in Boise, Idaho, as we have very few stores that sell good denim, and most of them sell the typical "expensive" jeans like 7 For All Mankind (by the way, I bought a pair of these because they fit well, and although the denim was significantly heavier than AG Jeans, the riveted corners of the back pockets begin to separate from the jeans after a matter of hours, and I had to have a tailor reinforce them), Citizens of Humanity, etc., so I have to order online.
I tried the Matchboxes in a faded blue (maybe 3 year? I can't remember the exact model) in my size, and immediately upon putting them on I was in love. Out of the box, they fit my waist and thighs fine, and the calf fit was also good. After a couple of days of wear, the thighs stretched out a tad bit, and now they fit just like I was looking for. They also make my butt (which isn't flat, mind you) look good. The denim is amazingly soft both inside and out, and I find myself rubbing my hands on the jeans just because it feels so nice.
The only downside is the fade. I really do want undistressed or raw jeans if possible, but like I said, I have to take what I can get. It's grown on me. It might not look good with "classic" outfits, but there is definitely a use for some pre-distressed jeans in my wardrobe.
Since then, I've purchased their Matchbox jeans in Beechwood (undistressed tan/khaki), Super Black (undistressed black), Jack (undistressed indigo), and 7 Years Grey (distressed grey). The Beechwoods needed a couple of days of wearing high to stretch them out. The Super Blacks needed about half a day of the same. The Jacks fit a bit odd, but I have no doubt they will stretch to a desirable fit. The 7 Years Greys were almost perfect out of the box.
I think the reason these jeans work for me and my slightly chunky thighs is the 98% cotton/2% polyurethane blend, as well as the weight of the denim. It allows for a very comfortable fit, and once they stretch, they fit great.
I have no hesitancies regarding quality. Although I don't wear these for work, the workmanship seems very good, and despite the lightweight denim, they seem like they will hold up for a long time. The weight makes them great for spring/summer/autumn jeans, although I've worn them in winter and don't feel cold.
I'm posting this in hopes that searchers, lurkers, and members will be able to find good information on these jeans. It's difficult to get good reviews that detail the fits, especially for people like me who carry their weight on the lower half of their bodies.
Let me know if you have any questions. Hopefully I was of help.
