So this discovery came from the day after i cleaned my entire apartment, my room, the bathroom (i scrubbed every corner), and had a full body shower. The next morning my shirt literally smelled like vomit towards the lower part of it and I thought my water was rotten because i got my shirt wet washing my face. I didn’t think anything of it and just took a shower. This morning i smelled that smell again but couldn’t find it. I lifted up my sweater and noticed like orange around my belly button and cleaned it including the use of rubbing alcohol. It did smell similar. my sweater doesn’t really smell like anything, but my shirt was thrifted. Idk if it’s me or the shirt atp and i’m going crazy.
