I have stuck to CBD blues and stripes and probably won't deviate much from this going forward.
Pale blue poplin: Smooth, lightweight and crisp, like it should be. It irons easily and stays fairly wrinkle free, but probably wrinkles the most out of all my shirts (which really isn't a lot). Nice shade of blue.
Light blue university stripe 100/2: I love blue and white striped shirts in all sizes. These are pretty small stripes at 2mm. I think the width of the stripes goes Bengal>Candy>University>Pencil. This irons well and stays quite wrinkle resistant throughout the day. Definitely a staple.
Light blue bengal stripe 100/2: I don't know the details of the fabric, but this shirt is super soft and is practically non-iron. In fact, aside from the collar, I didn't even iron the shirt the other day. It holds up very well throughout the day. I'd love to know the specs of this fabric and what other shirts are made of the same fabric. These are wider stripes at 5mm.
Luxire Privilege Collection Blue Herringbone: This is a fantastic fabric as well. Super soft and the herringbone is very, very subtle. For all intents and purposes, it's a plain light blue shirt. It's not quite as wrinkle free as the aforementioned bengal stripe shirt, but a quick once over with an iron and the shirt stays nice all day long.
I have ordered the light blue dobby twill and will report on that. I am also looking forward to trying some of the Monti shirts as well as the light blue university stripe.
If anyone is looking for a few staple blues or blue stripes, I definitely recommend the above.
