If you must have
Sky and don't like
Skylar, then
Schuyler nn
Sky is alright.
But I prefer
Skye. I think
Skye has more substance and attitude -
Sky seems pretty spaced out to me, pun intended, unless it is a nickname for
Skylar or
Schuyler.
My opinion:
Skye >
Skylar >
Sky >
Schuyler
I think all forms of
Schuyler don't seem fresh anymore, but they were never a big fad in the first place so I don't think they seem dated.
Summer and
Sky is really the only pairing that doesn't work for siblings IMO.
