Fore some uf us, the suit without the suit jacket, is clearly not a suit. But, who doesn't want to see his beautiful suited man in shirt and tie? This is a nice compromise. Throw the jacket over your shoulder!
Fully suited is ideal, but after a long day at work, looking gorgeous, isn't it nice to see your man in his dress shirt, maybe a couple of buttons undone? Or in a fresh, crisp shirt, before the tie is knotted on? So suggestive, so sexy!
