I went from hair right down my back to a pixie cut. DH prefers it long but it's so much easier short. It's your hair do what you want. Just remember if you don't like it , it will always grow out eventually
Yes I posted a pic of the colour recently. I do love the colour so cutting all that off is another thing putting me off. The front is like the bottom left pic up there. The Kardashian one. Colour is like that too.
Mid length styles tend to take quite a lot of styling to look right - there's a reason why they only look good on 'slebs. And... I've found that friends go mid length from long as they want something radical but can't quite do take the plunge to the short cut, but then the mid length looks a bit rubbish so they grow it out again.
How does your dp know that he won't like your short hair?
