What a beautiful blouse- I mean, it really will show off one's personality!
A lovely breathable cotton/linen material will allow this top be nice and durable- although I always wash my printed clothes inside-out. It just makes sense.
When it comes to sizing, I would suggest ordering one size larger than what you normally would.
Whichever Season we find ourselves in, I believe this turn-down collar blouse will be a head turner.
