First of all, read the wiki https://github.com/Mhburg/AwsomeInventory/wiki

Still confused or lost?. Well I had some misconception before on what I could do or could not do with this mod. I wanted to have my pawns wear some normal outfit and during raids change to armor that was stored in some storage room or something, you CAN'T do that, It's different than Gear Up and Go + Better Pawn control combo. You can instead have your pawns carry two or more sets of clothing (normal cloth and armor for example) and swap between them.

Steps do that (NOW WITH IMAGES AND GIFS):

1 - Click a Pawn, Go to "Gear", Click "Open Loadout", then "Make empty loadout".

2 - Click "Apparels" (t-shirt icon) or "All items" (Infinite or sideways eight) on the right panel.

3 - Select items/cloths you want, for this example select "T-shirt", "Pants", a hat if you have one, "flak helmet", "flak pants", and "flak vest".

(OPTIONAL) Close the Loadout window after this and the pawn would soon go get the items and follow vanilla Assign rules (if you don't create costumes), equiping flak items)

4 - In the Loadout window click the big C top left of the window between the gears and wish list. It will open the "Costume settings" window.

- (In this screen you will make all the outfits you want, for example work outfit and armor outfit, but only with the items you select on your wish list).

5 - Click "Create Costume" and name it as you want, for this example name it "Work Outfit".

6 - Select the items you want for this outfit, for this example select "T-shirt", "Pants" and a hat if you have one.

7 - Now click "Create Costume" again and name it "Armor Outfit".

8 - Same as 7 but select the flak items, "Flak Helmet", "Flak Vest" and "Flak Helmet".

- (At this stage you created one outfit with two costumes, you can change it as you see fit on the Gears page of every pawn, do some testing to get familiar with it)

How to Hot Swap (useful for raids):

9 - Have the pawn wear the "Worker Outfit" costume and RIGHT-CLICK the T-Shirt Button(HotSwap) bottom of the screen (where draft/undraft is. You need to have Hot-Swap actived on mod settings)

10 - Select "Armor Outfit" on the tiny menu.

11 - Now you can left-right the HOTSWAP button to immediately change from Worker Outfit to Armor Outfit. While HotSwap actived the arrows will turn blue. Click again to deactivated HotSwap and the pawn will wear the previous "Worker Outfit" costume.

TIP: You can click the Hotswap Button BEFORE or AFTER drafting, it doesnt matter, if the arrows turn blue the pawn will swap for the outfit you select when you righ-clicked it. You can then UNDRAFT, automatically deactivating HotSwap and the pawn will immediately swap for the previous costume "Worker Outfit".

Second Tip: Sometimes your pawns will not go get items from their wishlist. Mod conflicts aside, it can be because these items are outside of the pawn assigned area. Or because these items are of worse quality than you select in the wishlist (default being normal-legendary, so pawns will not get poor or awful items). To change this open pawn Loadout and click the gear of the item and change the slider.

Third tip: Usually your pawn have a limit of 35kg they can carry (based on their body type, don't quote me on this) use mods like Mercer's Backpacks (Continued), [WZRD] Carry Capacity (Continued) and I really recommend "Bulk Carrier". In fact I use all 3 (I would recommend lowering 150 carry capacity from "[WZRD] Carry Capacity" to 75, together with Bulk Carrier will make your pawn carry 37KG, only 2KG more than Vanilla, but now you can exceed vanilla hardcoded 35KG and carry more with backpacks, prosthesis, exoskeletons, etc). Bulk Carrier basically changes how carry capacity and carry mass are calculated and Carry Capacity is a easy way to tweak it how you like and not be too OP (Bulk Carrier gives you settings you can tweak too).

Why would I recommend these mods? Because Awesome Inventory forces you to carry all the clothes, armor (and items) you want in pawn inventory, limiting what they can haul or do.
