Okay, but tell me, what's wrong with wearing the same outfit two days in a row if it's not...

there's a thing called a in house washer and dryer, also fabric spray

You didn't get my point, did ya? (￣∇￣")
Also, not everywhere is a dryer and/or fabric spray a thing... ┑(￣Д ￣)┍

Ah, sorry.
I didn't see it fully (￣∇￣") Apologies, I have bad eyesight and am getting glasses soon. But yeah I agree, There's nothing wrong wearing it two days if that's all yout have on hand or didn't plan. It's not like it's a crime ╮(￣▽￣)╭ Plus washing clothes everyday wastes alot of water and heat especially if your poor or on a budget! I, myself plan outfits for the week and was my dirty clothes on the weekend.

Lol, I see xD
Exactly, having to wash lots of laundry is a waste of water and money (〜￣△￣)〜

I think its depend on where are you from. Im from South Asia, and in most country here we would bath 2-3 times a day, so after taking a bath, its does not feel right to wear the same cloths again. Even tho its not smelly, but on our mind we think its unhygienic to wear the same cloths for a long time. But its different for outerwear like jacket or blazer, we will use them 3-4 times before throw them into washing machine. (But not continuously coz we dont want people know that we have not wash them yet)

Hmmm, I see. It kinda makes sense, but holly shit, the water bill...

Surprisingly here, the water bill quite cheap, in my house that full of 6 person, the bill around 4 days of 3 times meals a day, even tho we use water so much in our household, cooking everyday, washing dish (handwash), toilet(we use water to wash ourselves after taking a dump or what XD) do laundry everyday. If u re normal student in a household of 8 (based on my uni life) it only cost you around 2 days of 3x meals .

Omg, good for you, otherwise you'd get broke fast just by washing clothes xD
