Gazelle have some nice options:

Velorbis (DANISH):

or you could get something like Specialized Globe, not quite ‘dutch/euro’ as no dymano, wheel lock etc but they are lighter.
example 3 speed :

the daily’s look love in the flesh, though not pastel
Ridgeback Metro is a good value range and well thought out, I bought my mum one + a rack and pannier bag

of course you could always build something up from old mtb..
these used to be muddy fox courier and a GT talera.. respectivily
Basil do a nice range of saddle and panniers that you can match making for a girlie looking bike. Sau if you want to Girlie up a Islabikes Beinn..
blue one has done less than 10 miles and yours for £195!
could of course go for Pashley Poppy, expensive but they hold value so good resale..
