If you want a blazer in grey, the Bower Turbo Travel Grey Pinstripe Blazer is a strong pick. The cloth has fine pinstripes.

Throw it on over a knit for a relaxed look, or over a shirt and tie when you need more polish. With grey, a white shirt reads sharp and a light blue one reads softer. A blazer is the jacket you'll wear most, so pick one that works with the trousers you already own, like grey wool, tan chinos or dark denim. This blazer stands alone, so you can mix it with the trousers you already own. Since a blazer has no matching trousers, it has to work with what's already in your closet.

Add a pocket square. We make it from your measurements, so the fit is yours from the start.

It's made from 54% polyester, 44% wool and 2% elastane. The polyester helps it hold its shape and resist creasing. A bit of elastane lets the cloth flex as you move. If you'd like a matching piece, the Bower Turbo Travel Grey Pinstripe cloth also comes as a suit.
