I take what fashion journalists write with a pinch of salt, unless they are reporting on a fashion show or on couture.
They often trot out the 'crisp white shirt' and 'well-cut black trousers' stuff good in theory but you'll look like a waiter.
I like reading fashion articles, but I will wear what I like, but i might wear it slightly differently. I stick to certain brands because I know that their cut will suit me. Some brands tend to not suit me. I'm shortish and they might be too long.I'm angular and they might suit a rounder or curvier frame.
Pastel blazers can look great. I'm not mad about the bomber jacket.
