Essentially the same thing
I've already accidentally used the former a few times
Many ribbed sweater posts aren't ribbed in texture and just have a pinstripe pattern anyway (i.e. not knitted that way; stripes are printed on; though undertagged as post count for pinstripe_pattern ribbed_sweater : 38)
Open to reversing the alias or instead sorting posts out from ribbed sweater into the pinstripe sweater tag, but doesn't seem worth it. Ribbed sweater is a pretty old tag and closer to the JP Pixiv tags.
