that one is LV? hmm.. kind of interesting. It's very clean. You say the material is excellent but everything else stinks. What's the "everything else" part? Just curious.
For the Intarsias,
I reckon you just really need to know your own body type and your body measurements pretty accurately, also ask for measurements for your potential Intarsia.
You can't really gauge if the jacket will fit or not based off what your weight is.
For example someone stated they had a 39 chest, at like over 170pounds? you could have 39 inch chest @ 145 pounds, see how that just doesn't work.
Due to being a very slim/skinny fitting jacket there is many more factors as well.
Your lats will have a huge impact also on the fit, along with your shoulder width and deltoid thickness.
Hell even the circumference of your arm affects it, as the sleeves are really tight, if you want to look like a shrink wrapped sausage you wont be able to wipe your own ass after you take a dump or lift your phone to your own ear.
And if you have a sleightly "rounder" "non atheletic" or very "bulky" body type, I personally wouldn't advise on going for the jacket, it just makes you look even fatter or full of water.
So....try it first if you can.
If not make sure the measurements will work out for your body.
If it's tight around the middle you probably need to lose the extra weight rather than hope the jacket stretches. You should have room to spare in the bottom and then it should be pretty tight as it goes upwards, otherwise like shdws said it's going to make you look fat. I don't know why people say quality has gone downhill, in my experience it's the same now as it was in like 2010 with the exception of the zips and strap.
