GAF, I am in the direst of fashion straits that I've ever had the misfortune of being in.
The good news is that I just got hired for a great job that I'll begin next week. The bad is that it's business casual - the type that requires you to tuck your shirt in.
That might not sound like a big deal, but I'm 5'11" and 260 lbs (i.e., overweight). My whole sense of style up to this point has been designed around the idea of wearing untucked shirts that mask the contours of my body, but that's not going to be an option anymore.
I have no idea where to even begin. Online shopping seems like a terrible idea, because I need to try on clothes to know if they look right. What brick and mortar shops should I be checking out? Are there any pro-tips for tucking in shirts without accentuating paunches? I really don't want to be self-conscious on top of the stress that already comes with starting a new job, so I'm open to any and all suggestions.
