It's probably time we move away from the conventional lower wear (read denims) toward more contemporary and comfortable forms of bottom wear.
Menswear brand Invictus offers trousers keeping in mind the modern fashion requirements. So you will find a lot of crop pants, ankle-length trousers and skinny fit trousers. But what's so unique? Even their formal and semi-formal trousers are 70% viscose or polyester, which is very rare to find. Buy yourself a polyester and rayon blend navy blue textured trouser, which people might even mistake for a running pant if not worn with the shirt tucked in, because of the solid blue panel around the lower hip. Go for something equally trendy like a charcoal grey and white slim fit checkered trouser with a drawstring closure!
Now, when we say all these can qualify for occasion as well as office wear, we are not even kidding. Try grabbing a two-tone stretchable semi-formal shirt which is a polyester, linen and spandex blend (yes it sounds crazy!), but the black sleeves completely in contrast with the coral blue colour of the whole shirt certainly stands out. And yes, it can be worn for an after-office party at a nightclub!
