Better question: what’s wrong with being butch?
Not at all! I have a friend who goes by [name_u]Merritt[/name_u] and she wears it well. It’s a rare virtue name that, in my mind, is really mostly feminine in nature.
[name_f]Ella[/name_f] [name_u]Merritt[/name_u] is adorable. I love it and [name_u]Merritt[/name_u] does not seem masculine to me at all.
I think it’s totally fine! Especially considering it’s a middle name, though it’d be fine anyway. [name_f]Ella[/name_f] [name_u]Merritt[/name_u] sounds great, and definitely sounds feminine if that’s what you’re concerned about.
