Would love to go see that jacket in person, I wish Atrum wasn't in Utsunomiya!!
Here's a short bio:
Avialae is a new brand by people from The Viridi-Anne. Yes they have a couple of leather jackets coming out next season. They've done clothes in the past 2 seasons and will continue to do some - jeans, collarless blazer, shirts, etc. also leather derbies. For AW14/15, you will be able to find them at IF and H.Lorenzo stateside, and there's also several international stockists (3.14, Chegini, Harvey's, Podium, SUUS, etc.)
btw, M.A+ does not always use Guidi - they sometimes use Montebello. same with Devoa, who has used not only Guidi, but also Montebello and Carlo Badalassi.
I think that you just have to learn to live with it. You can get the stains out by using an alcohol to soak them out, and then retreating, if it is a heavier leather, but if it is light colored, or suede, this generally just won't work. As you know, I personally dislike those super light and light colored leathers that a lot of designer and #menswear brands make. That said, you've seen my Margiela, and that thing has had oil splashed onto it. I use diluted alcohol to get the stains out, and then just retreated with leather oil. It will be darker, or course. I think that you need to think of leather more like denim, than like fine suiting. It will bear the signs of wear, one way or the other, so imo, I much prefer leather than looks good beat up and worn down.
