This platinum won't be handed to you. There are multiple trophies that must be done legit. Only 2 though that can not be done with a save other than your own.

Step 1: Complete AT LEAST Chapter 1, Chapter 2, and the beginning of Chapter 3 on any difficulty you wish on YOUR save. (I recommend you just play the game legit on easy first)

Optional - Choose either Chapter 1 or Chapter 2 to find all peppersnouts for their chapter.
This is optional because Step 2 will get you this trophy, but to make it look legit, do it this way.
This will get you
Nothing Like the Smell of Bacon - Pepper All Snouts in a Chapter

Next find all 4 Radula rooms in Chapter 2 OR play the game until you find 4 total.
This will get you
Shooting the Moon - Collect 4 Jars of Rose Paint

First Vent you find - Float on it for 7 minutes.
This will get you
Venting Frustration - Spend 7 minutes on steam vents

After Beating Chapter 2 go to the menu - press square and equip your newly acquired dress then back out to the menu.
This will get you
Dress-Ups- Equip a Different Domain Dress

Play chapter 3 until you get the Tea Pot Cannon
This will get you
Death by Darjeeling - Acquire the Teapot Cannon


During this step you should also get

Trophies that must be done legit that you can do during this step:

Neighslayer - Hit 4 enemies with a single Hobby Horse ground smash
Cold Arms, Cold Heart - Defeat the Drowned Sailor without taking any damage

Step 1A/ Step 3: Only follow this step next if you did a complete playthrough of the game. If not refer to this step after step 2.

Do these trophies before moving onto the 2nd half of this step.

These trophies must be done legit and can be done using chapter select
Chapter 3:
Final checkpoint in chapter 3, left side of the steps on the statue, shrink and stare at the glowing horse until trophy pops.

Pulling His Strings - Defeat the Dollmaker without taking any damage.

Use this glitch:
First start a New Game+
After the first save point (The Clock on the bottom right side is gone). Quit out to the main menu.
Go to chapter select and pick the last section of that chapter. Beat it and let it roll you over to the next chapter. Let it save, and then quit to the main menu. (The Beginning of the End should pop)
Repeat step 3 for the next 5 chapters.
In chapter 6 you do not have to fight the last boss. Just choose the last sub chapter in that chapter and walk to the end, The credits will pop and this trophy along with any other difficulty trophies you didn't get. This will also pop Level-Headed, if you didn't use it more than once. (Note: You do not need to use Hysteria to get level headed, nor do you need it)
This will get you
The Imaginative Endure - Complete the Game on Normal Difficulty
The Persistent Flourish - Complete the Game on Hard Difficulty
The Beginning of the End - Complete Chapter 1 on Nightmare Difficulty
Madness Prevails - Complete the Game on Nightmare Difficulty
Level-Headed - Finish the game using Hysteria only once

Step 2: Load the save in the Snouts folder

This gets you
