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.
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.
