first you go to the stairs where the Pokemon center is (left) and go down there, all the way until you see a man in a team rocket suit, he will give you a suit when you talk to him.
During the team rocket radio tower incident in Goldenrod City, you are not allowed to enter the Radio tower because it is blocked by a team rocket member. To receive the Black suit (team rocket costume) go to underground and towards the photographer area (Northeast section). Talk to the Team Rocket member and he will give you the Rocket Suit.
Go to the radio tower and go up the stairs
In the underground passage near the photographer, talk to the Team Rocket member there.
Go to the underground tunnel, go forward, and I think on the first right there will be a person in a team rocket suit. He will give you the suit. Hope this helped!!!!!!!!!
go under gound and take a photograph they give u a team rocket suit then go to the radio tower
if you are talking about the team rocket person in the radio tower in goldenrod city first you have to go to the underground place then you will see two men in a photo booth talk yo one of them and he will give you a team rocket suit (YOU LOOK GREAT) then you go back to the radio tower he will say OK, but then your rival will challenge you.
you go to the underground tunnel in golden rod city then you talk to the team rocket guy down there and he will give you a suit. then go to the radio tower and thee they are.
To get the team rocket uniform, to get in the radio tower. all you have to do is talk to the rocket in the lobby of the tower, he wont let you in until you have a uniform. So go to the underground tunnel and near the photo studio there will be a rocket who will give you one!
You need to go to the tunnel in Goldenrod City and there will be a rocket grunt there and he will give you a suit activating the event at Radio Tower.
Once you get to the part where team rocket is invading the radio tower, you have to put the team rocket suit on. In order to do this, you have to go into the underground tunnels under Goldenrod. The entrance is in the Top-Left corner of the city. go down the entrance to the tunnel and walk around talking to people until you meet the man who gives you the suit. YOUR WELCOME!!! GOOD LUCK!!! :)
you have to go to the underground area where the photography guys are. there will be a team rocket guy near the camer who will think you are a new recruit and will give you a team rocket suit. the guy in the radio tower will start to let you past until your rival comes and makes you take off the uniform. then you battle the guard and get to continue on.
In Kanto he is across from the desk in reception wearing a brown hat and suit. He will give you your upgrade after you fix the power plant
