You can instead choose the black & white comics patterns as proposed by Dolce & Gabbana, or they have their own because the ceck tartan and also the pinstripe.
I will never tire of repeating that fabrics must be of excellent quality, so linen and cotton are definitely preferable.
In short, having a blazer in your wardrobe is never wrong, indeed, I repeat, it solves the outfit for various occasions and is still a must have that cannot miss.
You can use it for a daytime look, in the office, in the evening combining it for example with a longuette black dress, earrings and elegant shoe, a clutch bag and you're done.

Have fun with your clothes and you will see that everything will be easier and more beautiful!
