Will this work to grow out my pixie haircut?

okay well im ready for my long hair to grow back! lol. I don't want to go through the Miller stage so I was thinking of growing it all out to the length it is in the back. idk how to explain this. lol I guess do you think it would look okay if I grew it out to like an a-line bob? all id have to do is grow out the top mainly. so its all to wear my hair is in the back. if that makes sense lol. im done rambling. hope you can figure out what im saying!/: bahaha
