It looks wonderful on you - frames your face, and your stylist did a fab job with the layering!
It looks like one of those cuts that you can go for months without trimming, if you want to add some length, and it will still look great in every phase. I suggest you play it by ear - see how you like it as it grows, then get it trimmed once you're no longer happy.
It's classic, and a keeper. Couldn't be more flattering!
