Question time!

So, I don't have a bob, but I did get my hair cut really short, with really really short layers haha. I've always had long hair, and would take a shower/apply product at night, throw it up into a high bun, and take it down in the morning. It was so simple/maintrnance free.

But, now that I have short hair, when I put it in a bun & take it out in the morning it just doesn't work. My layers stick out everywhere... suffice to say I need a new routine. I tried pineappling last night, but unfortunately that was a no-go as well.

So, does anyone here style their hair at night? If so, how do you keep your curls in tact until morning? TIA!
