This first one is a Punk Spike Studded Shoulder Leather Black Cropped Coat Jacket (details here). I really like the fact that the arms are covered with spikes, but not that it’s snake leather…
The second jacket is a black thick faux leather motorcycle one and it looks comfortable to wear but maybe too wide in the tummy area. (details here)
The third one looks really special, because in fact it is. It’s the result of a collaboration between famous lookbookers Lina Tesch and Masha Sedgwick. You can find it on Romwe.com (there are even stars between spikes!)
The fourth jacket looks exactly like an armor. It’s really nice along the chest area as on the shoulders as well. Details on Ebay here.
