I don’t dislike it – I do think I’d mishear it as [name_m]Stanley[/name_m] though I like [name_f]Sunny[/name_f] more but I see the appeal of Sunley and I think it’s definitely usable! I like the bubbly, warm and on-trend vibe. I’d stick to the Sunley spelling.
Visually and in theory; I love it! It feels sunny and approachable, much like [name_f]Sunny[/name_f] and [name_f]Hadley[/name_f]. I do think of the gymnast [name_f]Suni[/name_f] [name_m]Lee[/name_m] a lot but I don’t know that that’s a bad thing. I think I prefer just [name_f]Sunny[/name_f] myself, but I do find myself liking Sunley more than I expected to! It’s not my normal style but it is really lovely.
