Any input on whether this is the real deal? I found one for sale online that is the same which says it's late 70's but it showed no pics of the tags for comparison.
Hello and welcome to the forums. We can't authenticate here, you're best to take it to a YSL expert so they can it in person but this jacket looks more '80-90s than '70s to me. The label is similar to a '90s one in the VFG Label Resource. See here.
