If you like but can't get your hands on these sold out items, I found this Leith turtleneck and these Louise et Cie booties as alternatives to the Vince Jersey Turtleneck and Stuart Weitzman Perfection Booties.

The Leith turtle neck is a bit shorter and more boxy than the Vince but I like it, especially in burgundy.

And the Louise et Cie Booties have a bit lower heel and seem more comfy to me than the Stuart Weitzman. But I have yet to try the SW in my size since my orders have been canceled twice already. Third times a charm.
