The most obvious 'outfit sharing' - Shai has taken Tamer's original halloween outfit. Because Tamer does not have a Ram Horn or a Gloomy Fox, she got Fairy Jackie.
Years later, Shai adopts the outfit. On top of this, all of Tamer's halloween Cosplay Box outfits are Shai outfits (Florchestra, Skippity Hoppity), but she is permitted to get Vespena/Demonic and Angelic Queen/'Mature' variant of Bloody, Pumpkin, etc. It feels (yes, thats an OPINION and not fact) like Tamer as a class with cosmetics has been cornered into a 'yes and no' category; forced to only have the Shai wear for Cosplay, as the other outfits for other classes might not be suitable for her youthful appearance but gets to have non-class specific outfits like Shelle Belle just fine... wait, huh? 

Case 2: Jewelry and Accessories

Unique hairpin aside, as Shai also has Dumpling Headdress and Fleece Hat as a normal helmet, Tamer has NO earrings or facial piercings.
Every time you see a Tamer with earrings in, it will be the all-class items that are found during events.
Understandably, Shai has no facial piercings - those reasons are not relevant to this thread - but Tamer lacks earrings all together (besides the extremely rare Water Lily earrings which were release ONCE in the shop as a 40 eur bundle and then once more in a Twitch Prime code), as well as facial piercings.
If facial piercings are an option for non-Shai females, but Shai gets a variety of earrings, why is Tamer left with neither?

Case 3: Sharing 'exclusive' idles shoves Tamer further into a category which she is only a slight part of!

As there are many different idles in the game for hundreds of outfits, you will just have to trust me if you do not play Tamer first hand. However, I hope the above image can convey what I am trying to tell you - Tamer has exclusive 'emotes', sitting animations, outfit idles, and even a unique death animation. She was the only flat-footed female class, and has the cursed Short Cape. Since Shai now shares all of these, it feels like they are now stuck in their own category together. If the similarities run this deep, then why are cosmetics so different? If you ask me, I think Shai should have gotten her own set of animations to avoid this.

Bonus Case - The flute stabbed into Tamer's back.

- Going forward, offer the Shai equivalent of the outfits to all female classes. For example, the Shai version of Kibelius and Marine Romance is just plain superior, and I'm sure other classes would prefer it over the 7eleven bag we currently have. This one is a little more unfair as I know Shai love having their own thing and have gotten some elements like Bard-ing and global horse whistle taken from them to share with everyone else - but thats an adjacent topic for a Shai to make in a new thread as this is about Tamer only. Don't be awkward plz.

Why did I make this post?

Tamers unite!

We are kind of in between identities as far as cosmetics go. I do hope at the very least, we get access to actual accesories. You worded and voiced the plight perfectly.

Yes plz i'm want the shai version of the new halloween outfit on tamer ~ !!! OwO

The tail from the shai version of the wonderland outfit is so cute<3 I would love to have it on tamer if it fits on her character model.

The shai Taebaek outfit looks much better than the "normal" version too. It's annoying that we don't have both options to choose from.

Maybe for Christmas please? :)

this outfit fits so well for tamer! why pa why....

PA decided to give us 2 options of outfit swap with shai that aren't popular but an outfit that would perfectly suit on tamer isn't available for us. GRRRR

I insta bought that wonderland oufit for Shai, best outfit ever, it's just so adorable. PA could of gotten twice the money of me if only Tamer had the same outfit.

i guess we can only hope for an outfit swap that includes this ...
