I love the name [name]Tess[/name], but want to use it as a nickname. I don’t like [name]Theresa[/name], and Contessa (which I also don’t want to use) is the only other name I can think of that includes “[name]Tess[/name].” Any thoughts out there?
What about one of these?
[name]Theodosia[/name]
[name]Tessa[/name]
Teshura
Teshuva
[name]Therese[/name]
T”resa
[name]Tereska[/name] ( & [name]Terezka[/name])
Ter”zia
[name]Terezie[/name]
[name]Elizabeth[/name]
HTH! ^^
[name]Thessaly[/name]?
I love [name]Tess[/name] too but quite like it on it’s own, or just [name]Tessa[/name].
Good luck! 
i like [name]Tess[/name] and [name]Tessa[/name] as well but not any of the longer names which come to mind. i think [name]Tess[/name] is fine as a stand-alone name.
[name]Just[/name] [name]Tess[/name] or [name]Tessa[/name] are my picks as well
