I'm late to the party on this one but managed to find this in stock in L size at Rivet & Hide, most places seemed to be low on stock at this point. Anyways posting to share my fit and see what the experts think.

I was a little worried it was going to run a bit short in the chest. It's a little snug across the chest when buttoned, but the fabric is not too unforgiving and overall feels quite comfortable. I can still button up the jacket with a heavy flannel underneath and it's not uncomfortable, just enough room, and with a tshirt there's plenty of wiggle room. It seems like length to waist is about right (sits just below jeans waist line), and arm length is bang on (maybe a cm too long, but perfectly fine). Sizing up would have certainly meant the arms would be too long, so I reckon this fit is exactly right from the available sizes in this jacket.

Please excuse my pairing with cheap stretch jeans, I'm workin' on it

Also Ross from Rivet & Hide did me a solid and measured this before sending out, which confirmed it ran slightly bigger than their listed chest measurement and gave hope that I'd squeeze in. I've had great experience with R&H and IHUK so far, top work.

I think you can see it runs a little snug across the body / chest when buttoned up, though sizing up would probably be too big I reckon. Certainly too long in the arms. Probably better to be slightly snug than baggy. What do the denim sages think?

• When considering inseam length for hemming how much inseam shrinkage should we generally allow for? (may vary by fabric)

• Is hemming unworn/unwashed preferred, or is it better to wear/wash prior to hemming?

• Does vertical shrinkage also affect the rise of jeans, or is it more noticeable on the inseam?

I was wondering how much shrinkage to allow for in the inseam in some SBG 8301's that I'll send in to IHUK for hemming soon. And maybe hemming is a common enough question to warrant a FAQ. SelfEdges website says to expect .5in shrink in the inseam, I assume this is the same sanforized SBG fabric in other IHUK jeans, and IHUK details suggest minimal shrinkage. I'm sure people here have experience with this to comment how much shrink to expect and any other considerations.

My preference would be to send them in unworn / unwashed, since they're stupid long for me to wear without hemming first.

Here are the jeans in question on SE site:

It seems like .5 inch shrink would be too small to noticeably affect the length, especially if wearing boots. So I'm probably overthinking it. But as they say, measure twice cut once.

Aside from any shrinkage considerations finding the right inseam length seems fairly common sense. Make sure you wear the pants at the waist level you normally would, and make sure the inseam length is long enough to be comfortable for both standing straight, and crouching down on your knees / sitting down. And to wear the shoes you would normally wear. Ideally finding the best balance of not riding up too far showing your ankles if you crouch or sit, while also not pooling on top of your shoes when relaxed.

It arrived, and it fits 

you definitely wore it better though, broader shoulders, and that indigo shirt goes nicely. Need to get myself a tee with a bit more blue in it, this was the closest I have.

*mental note, photos next to a standing desk makes me look like a midget  to be fair I'm only 5′ 7″ so not that far off  ::)

Another shot, nice fabric in hand this moleskin.

@ARNC Yeah feels like a winner to me, looks like you got a good fit in the black thread too. IH makes a kick ass type 3!

Thanks, yeah it's a really nice soft feeling fabric in hand, and my crappy night time photos don't do it justice. Really happy to have been able to get this piece, I foresee it returning in future due to demand

Looking good Paul9221 and T4920!

@endo:

what a wonderful jacket! so soft, and the colour IMO a perfect match with indigo

looks sick, and great fit

I managed to find a M at ironheart germany, here's hoping mine fits as good as yours looks

Good point good point! I forgot there are other stockists

there is hope yet, thank you

No luck so far, but looks like a lot of stores haven't listed it yet either. I've been watching for this one like a hawk, looks like volume was quite small for this release or it sold really fast. Caught me sleeping on this one, literally, with southern hemisphere timezone it was released overnight for me 

Medium sold out already?  ???

Dang it, L would be too long in the sleeves for me

Yeah I really like the cut on these compared to some of the other 666 and 777 cuts, a bit of extra room around the thighs is nice, while still being fairly straight in the leg, not too much taper at the leg opening. In my photos the leg openings almost look a bit flared, but it's just how the fabric was puffed out a bit when first putting them on. I could pat them down and they would look straighter. I was fairly conservative with my inseam length for hemming, being the first pair I have got hemmed I didn't want to come up short. Should hopefully pan out fine with a bit of stacking after a wash. Can always do a little cuff if needed.

In hunting for a pair I noticed a lot of the other 666 / 777 cuts ran a bit low in the rise for me, or were too narrow in the thigh. There were a few that come close to these proportions, but weren't in stock. The IH-634S-SLB is also pretty close to this, quite a similar cut, tiny bit more room at the thigh and knee. Gives the possibility of the straighter overall look for those that want it, though perhaps a little roomy for me in the leg. Interestingly the IH-634 original denim is even more spacious in the leg opening / knee / thigh, I had considered them previously but figured 9in leg opening would be a bit baggy for me. IH seem to have figured out a nice middle ground with these SLB cuts. Works great for me, not sure how the taller folks find it.

haha I did move the coffee table actually, looked weird being half in the shot. Looks weird still. Need to find a better spot for photos tbh, but it's the easiest one
