OT but since RO is brought up in here, can I get some sizing advice via DRKSHDW non-leather piece?
I recently tried on a size 50 Mollino from this F/W I believe and it was a tad small, shocked. I mean it fit and I can put my arms in the sleeves, zip up the jacket but it felt maybe a bit tight to .5 size smaller. So, does the leather stretch? Arms were quite slim and zipping it up was pretty sleek in the body/midsection. Sort of have a better understanding of RO now and the fit. I always thought I would fit a 48 since I am usually a small-medium.
I am thinking about a non-leather piece in size large, 97/3 cotton, elastane mix. Medium is available but after trying on size 50 in the leather mainline, I am wondering if I am large in RO, generally. Sleeve length FWIW on the 50 was also good. No monkey arms business.
The jackets in question:
