I think Darren Lockyear is dressed by Cloakroom/Pistols at Dawn. A Brisbane based clothing company. I think he has been wearing a knit or plain grenadine tie as I think they stock a few there made by Dormeuil. He sticks out like a saw thumb when compared to his peers.
The judges on the block, dont dress too bad, Neil dresses a bit better than the younger guy. Wish they wore some pants other than just jeans though.
I swear I saw darren wear dub monks during origin 2. I also watch him when the broncos play and he only had like 3 ties. 2 glen plaids + I think a maroon one
