So it personally annoys me when a character has the same outfit (especially in some kid cartoons where they sleep with their day clothes and shoes on) so I am aiming to have every OC in a different outfit depending on the situation. It might be a pain but it’ll prevent me from yelling at the screen while rereading it.
Ohhh, finally, a topic to discuss!
I have my comic series in western cartoonish style and tend to follow it in character ddesigns but still I'm soooo fed up with toon characters having only one look for season so I decided to go more variative. I do still have that one, iconic, as you said, most recognisable character outfit but through the chapters their looks differ a lot.
My characters do sometimes change outfits, mostly when it make sense. Like when they go to a colder/hotter area or when their clothes get destroyed
I like to vary them because it could also show personality that isn't said :"o i don't have a comic yet but I plan to have my characters wear different outfits to also show a change of day as well.
Example i guess? This character has a methodological approach when it comes to his clothing. It's characterized by monochromes and blues/violets (just muted colors). He doesn't wear the same outfit most of the time but his pieces can be similar because of the combinations he used. Like in the second one (the most casual he's in), it doesn't have his usual waistcoat but the lighter blue part of the jacket has a v shape. It's formal-looking w/o looking very out of place in their world and w/o looking flashy.
There's also this girl https://toyhou.se/428577.-lianna-montgomery/gallery?key=Bd0p3bef8a56ZOU6 who I love to draw different outfits of. In her case it's more to show how wealthy her family is (with the patterns and jewelry). In her case too, it's probably one of my favorites because I can use the way she dresses in certain situations/with certain somebody as a contrast (like how she's covered up in social events and how shes willing to show part of her back/shoulders in another).
The only exception I can think of are when it comes to the gods in my story. I don't think they actually have a concept of time in their part of the world so they're just stuck in one or two outfits. The two that change outfits are to show departing influence from the main god.
edit: sorry for the rambly text haha, I just like clothes a lot ><
Only one character in my comic actually wears something different every strip. Why? It's because of concept of the character, which is somewhat meta, and I wonder if the readers have figured it out yet. Although they seemed more curious about her strange hair and eyes. The titular character has different variations of the same suit which changes his look somewhat.
Everyone else just wears the same outfit which only changes depending on the situation.
I also like the idea of changing my characters' outfits, as I prefer a more realistic approach. However, I also like to give each character their own distinctive palette, which is going to stay pretty consistent.
For example, Adrian loves his biker outfits in muted earth tones and there's no way you're gonna change his mind about it :'D
You could see him in grey, black or muted blue sometimes (in the last pic, for example, he's wearing a grey shirt, thouh you can't really see it with all of that light 
), but overall he's mostly going to stick to green and brown.
In my main comic, the characters wear the same outfits. There's every day wear, pyjamas and outfits for swimming. That's about it.
Me too, i try to keep the silhouettes similar and especially the shape language. If i can't fudge the silhouettes, like for example in my second chapter and in my upcoming fourth chapter, then I tend to fall back on clothing choice, specifically collar choice. A character's choice in clothing is a greater personality indicator.
New here to TAPAS so I was like, hey I love this style so much just from this one pic. Lemme find and follow this artist com- ah- 
That aside... you have a fantastic style there. 
@TheDWrek83 omg hehehe, thank you so much, it's really nice to hear 
@IndigoShirtProd I absolutely agree! I especially like to throw some characters in very uncomfortable situations and indicate this not only with the overall plot, but I really enjoy absolutely changing their clothes to something very unusual (thus uncomfortable) for them 
I'm mostly have my characters wear the same thing,
sounds lazy, I know, but it does work for most cartoons, and it can allow for some funny self aware jokes,
It's funny and for the times we're living in, it doesn't surprise me. It actually fits because I am sure I'm not the only one during this pandemic that hasn't changed their outfit in a few days...a week maybe... xD And to be completely honest, I have multiples of types of articles of clothing. I will have the same shirt in different colors, a copy (or copies) of one kind of shirt or pants, etc because I have issues with just having one. Like first of all, I love even numbers, secondly, I like having backups so it's not unusual for me in the slightest to have the same outfits. SO, as a reader this makes me feel normal when characters do this xD
I vary them because they change clothes. But they tend to be in clothing that suits what they're doing.
The characters in Errant will change outfits, since it just feels right for the level of realism and modern setting of their world.
It'll also be used as a sort of storytelling aid, because what they choose to wear will tell you a lot about where they're at. In this current part of the story, we have Rekki in this ridiculous, bombastic kinda outfit that represents somebody trying to show the world she's a powerful hero with enough confidence to pull off chest-high-red-flared-sailor-pants and a cropped bomber jacket, and we have Subo in clothes definitely more suited to lounging around in than fighting. They'll be wearing different stuff when we get to 'tomorrow' in this story!
I do change up the looks with an eye to keep each character's "style" intact though. So like... Rekki always wears kinda warm and hot colours and her clothes always have a sort of tomboy/ladette/member of the spice girls feel. Like she's a bit sporty, a little bit britpop retro etc. Subo will always look like somebody you'd meet at an organic food market and wears all these earthy, natural colours and greens.
For me, I like changing up the colors of my character's clothing or the logos, whatever it is, but I maintain like 4-5 variants of a clothing design. Long sleeve tunic with pants, plain t-shirt with shorts or pants, a button up shirt with pants, tank top with shorts, and perhaps a sweater with pants. V-neck shirts and plain t-shirts are very abundant xD I want to make more kinds of outfits, though. When my characters go out, I try to vary their outfits more. I am probably gonna make a lot more sketches of outfits in my sketchbook since this thread has inspired me. But I don't find characters who don't change their outfit as strange. I don't mind it, personally. It is easier for the creator, which I can guarantee sometimes we do take part in the easier routes, which I can never be mad at or blame a creator for. The professionals have done it (example: characters who have only 4 fingers because it saves time) and it isn't illegal xD I find it funny when as @WhoDrew mentions, the characters are even self-aware of it.
Instead of drawing them in the same outfit all the time, I tend to prescribe a "style" to them, trying to maintain their color pallet, silhouette, and shapes. Like my main character tends to wear leggings and loose t-shirts, and I tend to keep her color pallet to yellow, white, and gray. I also try to incorporate some kind of heart shape somewhere on all of her outfits. Hopefully, this method lets her design still be recognizable while still feeling more "realistic"
Here's some examples of her same-but-different outfits:
