Everybody knows, that to be the best, you have to wear the best cosmetics.

To start out, you'll need your handy dandy Ghostly Gibus. If you deleted yours, you can still obtain a Ghastlierest Gibus, and change the style so it matches that of the Ghostly Gibus.

Second, you are going to need Flair!. This cosmetic matches up perfectly with the Ghostly Gibus, making it a powerful combo.

When you obtain your two cosmetics, your sniper should look like this:

The next part of our guide comes to picking the correct weapons for your sniper.

Any primary should work excepts for bows, since bows require 100% skill.

For your secondary, I recommend the Cozy Camper or Jarate. If you plan to equipt an SMG, make sure it's the Cleaner's Carbine for maximum meme.

Finally, for your melee, the stock Kukri or any reskin should do the trick.

Personally, I recommend the Stock Sniper Rifle, the Cozy Camper, and the Stock Kukri for your loadout.

It should look something like this:

Now that you've got your cosmetics and your weapons, it's time to head out on to the only map that you should ever play.

Turbine

Turbine is the best map for practicing your skill. The player skill level is mixed enough for you to practice. Make sure that in your casual queue, you have only Turbine selected.

Your casual queue(r) should look like this:

This step is 100% optional, if you don't like taunting after kills or spending that dosh on items, don't bother with this.

Now that you're a pro sniper, you can have the ability to taunt after kills. Some how, obtain The Killer Solo. After every kill you get, you should use The Killer Solo, so the person you killed will think "Wow he good saxaphone man" and will be jealous.

Everyone is now jealous of your cosmetics and saxaphone skills, now is the time to make yourself even more god-like with a simple profile edit.

Go to your steam profile, and select "Edit Profile"

Now where you have your profile picture, select "Choose from Official Game Avatars"

The next step is to pick your profile picture from the Team Fortress 2 Game Avatars. If you played the game recently, it will show up near the top, if not so recently, then you'll have to scroll down a bit.

Now from the list, pick one of the sniper profile pictures. Any will do.

One you have selected one, it's time to change your name. Scroll to the top of the Edit Profile page, and change your username to something generic, and make it all lower case. An example would be "thomas", "dan", or "luke".

Once you're done, click save profile.

It shoud look something like this:
