Hehe... he does look very good in those formal outfits. That is not because of the belly, either; the normal outfit has thi smart look, while the ALTernative outfit is looking very fancy, especially wi that coat! I also like the pants button above the tail.

Oh yeah! He's such a lovely lad.

It's a neat reference sheet. If he's like you then is the clothing style also of your tastes? I admit, I personally always feel a bit confined whenever I have to wear formal shirts. Of course it makes sense for him since he likely works at a place with his own desk and the sorts.
As said, the idea with the blue base colors going of your characters for your and SD's Slowking is also a nice idea. And as of the general design of Slowking, the neck ring adds to the somewhat regal appearance.
Saying that, the alt. outfit sure tops it off, giving your character the feel of a modern day castle owner.
The facial expressions are surely also nice to have here. Speaking of which though, with Slowking I feel like if they'd walk backwards their Shellder-kinda helmet really can give off a somewhat ghostly and imposing expression. <X3
If there is anything that I find confusing, it might only be the color sheet. I have that with my own reference of Shiny and I'm eager to at wanting to group the circles so people know what colors belong to where. Just feeling like artists would rather pick from the character itself rather than the sheet.

Seeing all this, I feel like you'd highly enjoy visiting one of those medieval fairs where people can rent such old style of clothing and watch horse riding tournaments, music perfomances and eat like in the middle ages. Though you already stated that you like that algamation of fancy old style and the comforts of modern times.

Rex drew your Lucas nicely here. Thanks for sharing.

Yeah, the clothing style is also of my tastes. I wish I could dress like that more often though. I rarely can. ;w;
What do you mean when you say you feel confined in such clothing? <:3
But yeah, very true! It suits him given his job. It also generally suits Slowking given their intelligence. X3

Yeah, true! I like how we’re a Slowking couple where one is shiny and the other isn’t. Makes it easy to tell us apart and is also a bit in line with Lockjaw and SD’s colours. X3
The neck ruff might be one of my favourite things about Slowking! :D Like I said, he does have a full one. He just tucks in the front because of his clothes for them style points. X3
Ooo, I like the idea of him being a modern day castle owner! Though where would he have gotten the money for that? X3

The alt outfit originated from a medieval RP I did with Simon. Turns out the suit isn’t so much medieval and more Victorian, but my RP means my rules. >X3

I like to think the Shellder allows him to see behind him. X3 Hey, he’s forever stuck with it, so might as well make use of it. X3

Yeah, and worse: I feel like some colours have been left out of the colour palette. One of my friends does group them for the ones he does though.

Huh. Maybe. I don’t think I’ve ever been to one of those. Do they happen in your area? <X3 But yeah, I’d love to try out one of those outfits!
And yeah, I do. It was a thing as early as with Lockjaw back as a Totoknight. X3

You’re welcome! I’m so happy you like Lucas, Marc. :D

I'm personally not a fan of clothing that I need to button up at a bunch of places, that sits somewhat tight to the skin or that consists of a bunch of layers. It's pretty much why I am usually happy when it's warm enough for me to not have to wear jackets and sweaters yet. A shirt and trousers of some sort are much more enjoyable for me personally. Other than Shiny I've never been much of a fashion nut myself. If the clothes are comfy and look alright, I'm usually fine. I don't really know anybody who would design something specifically for me or spend a long time comparing a bunch of different clothing pieces either.

Well, perhaps he doesn't have to own one but could always spend a vacation at one. There are castle hotels.

I wonder if he has like a channel in his mind that he can touch into to see what's up behind himself or if he needs to close his eyes and connecting. Though in real life it's hard to guess if you only possess one pair of eyes obviously. X3

Oh, they sure do. We got a bunch of castles here so every now and then I see advertisements for such medieval fairs. Admittedly never been to one though.

I see. I occasionally like that feeling. Hehe.
I absolutely refuse to wear polo shirts though. Those are ew. I hate them. If it's a T-shirt I wear, it's gonna be a normal one. But yeah, you do you.
Also, you say that, but you have that shiny Totodile hoodie.

Castle hotels, eh? I see! X3
Alternatively I was gonna suggest not applying logic to it so money's not an issue but eh. XD

Yeah, I've also always wondered how it works. I don't have 360 degree vision so I wouldn't know. X3

I see! Though I doubt they have those style of clothes there because according to a friend, they're more Victorian than medieval. <:3

Hoodies are pretty neat, I'd say. Personally prefer the lighter variant though. The costume hoodie of mine is something you should rather wear when it's colder definitely. I wore it usually during a later summer time on Pokémon events and even then I found it a bit tad warm in it after a while. But in a climated space it usually is pretty much a good comfort wear.
In general I think with sweaters/pullovers it can also depend. Some of them feel more leisure than others. Some can also be more of a tight fit or the material can be what makes them less enjoyable to wear.

Well, you could always just have it like "Luigi's Mansion" and happen to win one in a lottery. <X3

Oh, well, some of the more wealthy folks had more colorful types of clothing compared to the farmers as far as I know. There are interesting online articles on the subject of medieval clothing. I recall browsing the subject back when there was the suggestion in the room of that Don Quijote inspired knight and squire art.

Oh, yeah, that makes sense. :3 I don't wear my Totodile hoodie often due to the tail. XD
Yeah, true. But I don't know. I find it hard to explain, but a fancy dress shirt feels great to wear to me for some reason.

Maybe. X3

Ooh! Could you tell me more about this through notes? :o

I appreciate the footwear on him, hehe.

Glad you do! Isn't he just perfect? :D

I'm now wondering what attacks does he have?

I think he has Scald, Psychic, Fire Blast and Dragon Tail.
