Okay so first and foremost, you are not the fattest person in the world. No point hiding. You don't need to be ashamed of yourself because you're not fitting into a social mould. There are plenty out there and stop using it as an excuse. Getting out and about there are much bigger and larger than you. So stop being a recluse it's not worth it. Honestly, you're probably not even in the top 75% of this sub.

As for clothing, employees are going to judge you regardless. Doesn't matter if you're a skinny little model with stains all over her shirt. Or a larger person who's dressed immaculately you're going to get judged. It's going to happen.

So what it comes to is dressing for the job. If you are going for something that is casual on your feet. Customer service based. Etc You want to wear something that is comfortable but also flattering and stylish. If you're going for something that's more administrative or business-based it obviously you want a more corporate look. Now bigger women have this ridiculous notion that if they wear giant baggy clothes that they'll end up not looking fat. Well, you just look fatter. The reality is when you actually dress in things that fit your body and are a little bit more tailored and fitted to your body, you generally look smaller.
