I was thinking how I would name twin girls and made these three pairs:
• [name_f]Violet[/name_f] [name_u]Anne[/name_u] & [name_f]Hope[/name_f] [name_u]Louise[/name_u]
• [name_u]Esme[/name_u] [name_f]Caroline[/name_f] & [name_f]Lilia[/name_f] [name_f]Charlotte[/name_f]
• [name_u]Harper[/name_u] [name_f]Marina[/name_f] & [name_f]Maeve[/name_f] [name_f]Annabella[/name_f]
What would you pick? 
The first
Me too
[name_u]Love[/name_u] the names and combo!
esme and lilia !
[name_u]Esme[/name_u] & [name_f]Lilia[/name_f] are my favorite! They’re unique but still recognizable. I think they have great vibes individually while still being cohesive as a sister set.
I’d choose [name_f]Lilia[/name_f] & [name_u]Esme[/name_u] from your pairs 
If I’m creating my own pairs with your names, I’d choose [name_u]Esme[/name_u] & [name_f]Violet[/name_f].
Ooh gorgeous sets! [name_f]Violet[/name_f] [name_u]Anne[/name_u] is lovely, but I’m not such a fan of [name_f]Hope[/name_f], so I’d go with [name_u]Esme[/name_u] and Lilia; absolutely precious.
[name_f]Violet[/name_f] [name_u]Anne[/name_u] & [name_f]Hope[/name_f] [name_u]Louise[/name_u] are lovely. 
A lovely set of names 
However my favourite is [name_u]Esme[/name_u] + [name_f]Lilia[/name_f]!
[name_u]Esme[/name_u] [name_f]Caroline[/name_f] is sweet, feminine and has a pretty vintage flair. [name_u]Esme[/name_u] is beautiful such a sweet feminine choice with the most gorgeous meaning loved. I love [name_f]Caroline[/name_f] as [name_u]Esme[/name_u] middle name a lovely combination honestly [name_f]Caroline[/name_f] has beautiful sound with [name_u]Esme[/name_u]. [name_f]Lovely[/name_f] name!
[name_f]Lilia[/name_f] [name_f]Charlotte[/name_f] is absolutely beautiful. [name_f]Lilia[/name_f] is a favourite of mine she’s elegant, bright and has tons of pretty springtime energy. I absolutely love [name_f]Lilia[/name_f] such a sweet floral name. [name_f]Charlotte[/name_f] makes a beautiful middle name for [name_f]Lilia[/name_f].
I think [name_u]Esme[/name_u] and [name_f]Lilia[/name_f] sound gorgeous together.
[name_u]Esme[/name_u] [name_f]Caroline[/name_f] and [name_f]Lilia[/name_f] [name_f]Charlotte[/name_f] are lovely 
I like the link between the middles and [name_u]Esme[/name_u] is so warm and stylish and [name_f]Lilia[/name_f] is light and gorgeous. They fit well but hold their own
Different strengths: Violet & Hope is very story book pretty; Esme & Lilia is more daring and sophisticated/international; Harper & Maeve is the more hip and happening (but most trendy)!
Edit: I would choose Esme & Lilla but I may have chosen another combo a few years ago.
[name_u]Esme[/name_u] and [name_f]Lilia[/name_f] for me 
🫶🏼
Though… [name_f]Violet[/name_f] and [name_u]Anne[/name_u] are a close second. The third set are not quite for me, but they are still handsomely nice!
[name_f]My[/name_f] favorite is the second pair!
[name_u]Harper[/name_u] [name_f]Marina[/name_f] & [name_f]Maeve[/name_f] [name_f]Annabella[/name_f] - so sweet and spunky!
my favorite mix & match pair would be [name_f]Violet[/name_f] & [name_u]Esme[/name_u] or [name_f]Violet[/name_f] & [name_u]Harper[/name_u]! maybe [name_f]Violet[/name_f] [name_f]Annabella[/name_f] & [name_u]Esme[/name_u] [name_f]Charlotte[/name_f]
I’m stuck between 2 and 3, leaning towards 2
Oh, [name_u]Esme[/name_u] & [name_f]Violet[/name_f] would be adorable too! 
100% agree with you
[name_f]Violet[/name_f] [name_f]Annabella[/name_f] is such a pretty, girly and stylish combo 
I love names like [name_u]Esme[/name_u], [name_f]Amanda[/name_f], [name_f]Aimée[/name_f]. It’s just sooo sweet having a name meaning loved
[name_f]Lilia[/name_f] is the epitome of elegance to me too!
