I am leaning towards [name_f]Juliette[/name_f] because it seems more elegant and feminine and also emphasizes the “ET” in the prounciation, but wondering if it’s too frilly or what the trend is in spelling now?
I prefer [name_f]Juliet[/name_f] on most days, as it is less frilly. However if you do want to stress the ‘ette’ then [name_f]Juliette[/name_f] makes more sense. [name_m]Both[/name_m] are pretty. I also know a woman who goes by Liette which I think is so sweet.
I think both are lovely and pleasing to the eye. [name_f]Love[/name_f] the name actually. I think I slightly prefer [name_f]Juliet[/name_f] as that is more the classic spelling from the play and it gets the pronounciation across without looking unfinished or anything.
I think the Starbucks test would favour [name_f]Juliet[/name_f]. With email we probably spell out our names more than at any other point in history so I’d favour the more familiar Shakesperean [name_f]Juliet[/name_f] over [name_f]Juliette[/name_f] unless there was a fantastically good reason. As a [name_f]Catherine[/name_f] I favour making life as easy as possible when it comes to most common spelling.
What is the “Starbucks test”? [name_m]How[/name_m] is [name_f]Juliet[/name_f] without the extra t and e pronounced? is it still [name_u]Juli[/name_u]-ET or is it JOO-liet.
I prefer [name_f]Juliette[/name_f] because I love frilly girl names. lol.
I think [name_f]Juliette[/name_f] is prettier and daintier for sure. If I weren’t a theater-buff, I’d choose it hands-down. Unfortunately, I have to vote to respect the [name_m]Bard[/name_m] and go with [name_f]Juliet[/name_f].
[name_f]Juliet[/name_f] for me. I’m almost always in favor of the simplest spelling.
[name_f]Juliet[/name_f] looks polished and just right. [name_f]Juliette[/name_f] has always looked overdone to me. I feel the same way about other names as well ([name_f]Annabel[/name_f] vs. [name_f]Annabelle[/name_f], [name_f]Isabel[/name_f] vs. [name_f]Isabelle[/name_f], [name_f]Mirabel[/name_f] vs. [name_f]Mirabelle[/name_f] etc…). [name_m]Shakespeare[/name_m] made the grade. Sometimes less is more. 
[name_f]Juliet[/name_f]! I love it. [name_f]Juliette[/name_f] just looks like an overload of letters.
Basically, it’s a test to see how people might spell a name. Starbucks will often ask you to provide a name to write on your drink when you order and (from my experience with myself and friends) don’t usually ask for spelling. It’s a good way to see how people might assume how a name is spelled.
As for your original question, I like [name_f]Juliet[/name_f] better, but I don’t dislike [name_f]Juliette[/name_f]. For me, [name_m]Shakespeare[/name_m] is an influence, but also, I think that the super frilly -ette is a little overkill for me.
I love it spelled [name_f]Juliet[/name_f]. [name_f]Juliette[/name_f] just looks fussy to me, like trying too hard to be girly and frilly.
