Help!!!Can i have an updo?

You might have to get creative with it, but sure, you can have an updo at that length. The parts that are too short to sweep back, you can twist back along the hairline and secure with hairpins, or if they're long enough, braid them back and tuck in tiny flowers or decorative hairpins anywhere there might be ends poking out of the braid too conspicuously. When you reach the back, you could tuck it into a bun or something like a French Twist, or one of those cute little fountain twists where the ends aren't tucked into the twist, but left to sprout out from the top. . . Just take a while to play with your hair, try different ideas and different accessories, and see what you come up with.
