There are various ways to express the verb "fit" in Mandarin, such as 適合，配合，對 and so on. I'm not sure which one to use when expressing sentences like:
The clothes no longer fit me.
I need clothes that fit me.
The idea is that the clothes are the wrong size now, there is nothing else wrong with them. (不)適合我 seems like it could also mean "I (don't) like the style".
Would I even use a word like "適合" here, or an expression like 穿不上? Is it different if the clothes are too big instead of too small?
