Older fatherhood isn't all bad: testosterone rates drop about 1% per year as men age making them less reactive and more patient and a professionally established middle-aged man is likely to have more time and money to devote to his kids than a twenty-something who's just getting started.
I really like Calvin Klein for his classic simplicity. I also think Prabal Gurung designs some great pieces that work well for me. My mom has such great style she's my biggest influence.
I'm a fan of designers and clothes that look beautiful but more importantly make me feel beautiful and confident. It's why I've always loved Stella McCartney and more recently Prabal Gurung. Their pieces are cool yet timeless and the fits are effortlessly flattering.
