The Outer Worlds

Alright so all of these guides are kind of split up so I decided to write a more extensive version. EDIT: Make sure to check the comments for some more tips!

There are two clothing pieces you need as you can read from the achievement description:
-A Nice Hat
-Chimaera

A) A Nice Hat can be found outside of Stellar Bay on Monarch. It's in the church just south of the town.
As a reference this is also where the peace treaty will be signed between the Iconoclast from Amber Heights and the people from Stellar Bay. If you are going for the war instead, you can still see where Graham and / or Zora spawn. Go straight to the back of the church to find a skeleton wearing a chique top hat.

B) Chimaera is the reward of a 3 part quest in Byzantinium named "Makes Space Suits, Won't Travel"
1) Wear Spacer, Marauders and Iconoclast clothing.
2) Get 10 primal leathers, 3 Raptidon parts and 1 Mantiqueen gland.
3) Collect a parcel

If you cannot find the clothingshop where Celeste will give you this quest then follow Parvati's companion questline. Eventually she'll want to go shopping here and you'll get a questmarker. If you just want this specifically, this shop is somewhat in the middle of the city centre.

1) the important thing to notice is that it's not about faction colors or brand. It is based on the description. So it should say: ... spacer wear this ... Marauder clothing that etc. I recommend therefore to look for clothing pieces instead of armor pieces. Don't forget that you also need Head gear!
-Spacer --> NOT spacer's choice. Clothing that a spacer would wear. You can get this clothing in Groundbreaker at the armory in the back, not the one selling Moonshaped masks.
-Marauder --> Marauders themselves wear this, I picked this up when going for Iconoclast on Monarch. Some miner clothes will sometimes count for this, just check the description
-Iconoclast --> There is a guy you can save on the broken bridge of Monarch. If you help him out he will become a street vendor outside of Amber Heights. He sells what you need. However if you are not at war with the Iconoclast then you could go into Amber Heights and buy the outfit from the vendor there.

Once you collected the clothing pieces (3x2 total) you can show them off per set. The order doesn't matter for this

2) You can't get these before the quest updates. You'll get the items as quest items. That's also how you can keep count in between. Either Scylla or Emerald Vale will have the 10 primal leathers. The other creatures you can find on Monarch.
(If you haven't completed Nyoka's companion questline this will be a perfect combination!)

3) This is basically just following your questmarker all over town. Once you are done collecting the parcel, make sure to obtain the key and complete the quest by collecting your reward the Chimaera.


Now that you have both items, just simply equip them and your achievement will unlock. You don't even have to leave the menu so you can just equip your own stuff right back

You need to equip 'A Nice Hat' and 'Chimaera' at the same time.

'A Nice Hat': Head to the Stellar Bay Ruins and you can find it on a skeleton inside the Church.
'Chimaera': Complete the quest 'Makes Space Suits, Won't Travel'.To obtain this side quest, head to Byzantium and find Celeste in the clothing store.

The achievement is unlocked when you equip the Chimaera clothing and the A Nice Hat headgear at the same time. A Nice Hat is easy to find. The Chimaera armor is acquired as a reward following a fairly arduous side quest.

In anticipation of a side quest that comes later in the game, keep an eye open for three different armor (clothing) & helmet (headgear) combinations. Early in the game, you will come across Marauders. Ensure you have, at least, one Marauder clothing or armor and one Marauder headgear or helmet. The item’s description seen in the inventory screen will clearly state it is a Marauder piece of equipment.

The second combination is Spacer’s clothing and Spacer’s headgear. If you do not come across them as enemy drops or loot, you can buy them from Ike’s Armory in the Groundbreaker Promenade. Do NOT confuse Spacer’s equipment with Spacer’s Choice equipment. In spite of the similarity in name, the two are different. Spacer's Choice is a brand name. We are looking for the descriptive, "Spacer."

An example is Streetware, Basic made by Ports of Call. The description in your inventory screen will read, "Medium weight leather spacer's gear." A headgear example is Enclosed Padded Helm made by Aramid Ballistics. The description on your inventory screen will read, "Lightweight Spacer's helmet. Full coverage for moderate protection."

Finally, you will need an Iconoclast set. If you don’t come across the items as loot or enemy drops, you can purchase headgear and armor from the Iconoclast Quartermaster Vendor just inside the Amber Heights gate. The description in your inventory screen will clearly state they are iconoclast items.

A Nice Hat is available in the OSI Church just outside Stellar Bay on Monarch. Exit by the Stellar Bay north gate—from your ship, head straight around the Yacht Club. Sebastian is standing at a corner of the building. Looking ahead to your left, the gate is in front of you. Exit into the Monarch Wilderness. At the first sign you see, take a right following the sign’s arrow pointing towards Cascadia. The church will be a very short ways from the junction on your left. Enter and go all the way to the back. You'll find a skeleton wearing a top hat. Pick it up. This is A Nice Hat required as part of the outfit for the achievement.

When you get to Byzantium, go to Jolicoeur’s Haberdashery and speak to Celeste Jolicoeur. This is best done after you have started Parvati’s companion quest, Don’t Bite the Sun because you will have a quest marker directing you to Celeste. More importantly, you must complete the task Find Parvati Fancy Clothes before you complete Celeste’s quest Makes Space Suits, Won’t Travel. If you finish Celeste’s quest before you acquire Parvati’s clothes, you will botch Parrvati’s companion quest and miss the achievement for completing all companion quests.

If you are on the Halcyon Path where you tell Udom Bedford (the Halcyon ambassador on Groundbreaker) that you know Phineas's whereabouts, you will arrive in Byzantium before you land on Monarch. If this is the case, it is best to defer talking to Celeste until after you go to Monarch and acquire A Nice Hat and the Iconoclast clothing & headgear especially since you must return to Monarch to complete Celeste’s quest. You can wait until the story takes you to Monarch or you can force your way in by ignoring the warnings and land on Cascadia. From there, make your way on foot to Stellar Bay, Fallbrook, and/or Amber Heights. Once you have A Nice Hat and the iconoclast clothing & headgear set, you can fast travel to your ship and return to Byzantium.

I recommend completing the purchase of Parvati’s clothing before proceeding with Celeste’s quest. When you are ready, Celeste will ask you to model the three clothing and headgear sets—Marauder, Iconoclast, and Spacer. Do so. She will then ask for Mantiqueen Chitin, Raptidon Flank Hides, and Primal Leather. The first two are obtained on Monarch. Follow the quest marker—they are in different sectors. Go to Scylla for the Primal Leather. You might have a quest marker in Emerald Vale but I have not found the primals there to be a reliable source. You might have more luck, but the primals on Scylla should drop the leather readily.

When you return to Celeste with the materials she asked for, she’ll inform you that Halcyon Parcel Service (HPS) is experiencing delays delivering her trademark gold lapel—the garment’s final touch. Follow the quest marker to HPS where you get the run-around. The package is en route to the wrong destination. Follow the quest marker to the address only to learn the lapel has been returned to HPS. Go back to HPS. Go to the window to receive the delivery or pick the lock to sneak in behind the clerk and take the parcel from the counter.

When you return to Celeste, you find the shop in chaos. Your task is simple, though. Ignore the hubbub and take Celeste's Key (a quest item) from her. Use it to enter her office. Take the unique, named armor—Chimaera—off her desk. This completes the side quest Makes Space Suits, Won’t Travel. You don’t have to equip Chimaera now. When you do, along with A Nice Hat you picked up from the OSI Church on Monarch, the achievement will pop.
