To expand on Baja's succinct (and absolutely correct) answer: Your aloe is stretching in an attempt to get more sunlight. Position it as close to a south-facing window as you can. Rotating the pot a quarter-turn every week or so will help an upright aloe stay upright, but your plant will not get itself upright at this stage; it will correct course toward wherever the sun is coming from, so will be sort of S-shaped. It won't die because of the bend, but it could fall over unless propped. You can help avoid a top-heavy tumble by planting it in a clay pot that is shallower than wide. That plastic pot is begging to tip over.
The color and markings are beautiful and other than the etiolation (stretching) it looks healthy. In a nicer pot it could be quite lovely.
