But seriously, for me it's the Wingding Shirt and the Traveller items (except sometimes I find use for the accessories). The contrast and the shading line up really weird compared to some of the other items, and the Wingding's added curves cause clipping problems.
Chyaku Norisu, Dark Halo, Danklets... I never took them off way back then, but now.... sweatdrop
Problem is I'm a sentimental old packrat, and online is the only place I feel I can be a packrat. (In real life, I've worked veeeery hard not to be, since my grandmom's house was like something you'd see on Hoarders.)
I feel a bit funny 'cause a lot of items that people are posting that they never use anymore... I still like them :'3 (I still use Alruna, Lotus, and Death Whisper from time to time... was using Death Whisper before I changed for my Easter outfit, lol)
But items I never use anymore, but thought they were so cool back in the day:
Cookie Boots, Pixie, Cloud, Katana, Coco Kitty Plushie, Danklets, Wild Things, G-Blade....
Alruna's Rose. It just didn't suit my outfit because the items I placed it with were much more detailed. In order to keep things consistent I had to exclude the Rose.. so since it was obsolete I eventually sold it. It was such a good item before, IMO, when all we had were quite plain items. Them heels!
