I usually have a hard time with the fit of off-the-rack suits, thanks to my athletic proportions, but somehow Burberry always fits me perfectly. There's no tailoring really required, which is rare for me.
For me, what takes up most of the space in my closet are suits. I wear a lot of suits and jackets. But I think every man needs a black suit at home. You can never go wrong in a black suit. But in terms of style, I think it's about being comfortable in what you wear.
