I wear sweats to the commissary

So MSM appears to want to create Do's and Dont's lists for everything. If only life were as simple as a list. They asked milspouses to weigh in on what not to wear. This is NOT a new topic. Milspouses who have nothing better to do take great delight in putting down other milspouses clothing choices.
As expected, this turned into a judgmental free-for-all, with one woman going off on pjs/sweats at the PX and Commissary.  This is just the example I am focusing on, not the sum of all of the bitchiness.

I confess. I wear sweats to the PX.

You see, I work in a lab where I deal with chemicals that stain clothes, dissolve clothes, etc. Even with a lab coat, I occasionally get something on me. It is a waste of money for me to get dressed up to work in an environment where my clothes will likely get destroyed. After working for long periods, a few times over 36 hrs straight, I just want to do what needs done and go to bed. So I roll over to the commissary in my stained, dissolved, disheveled sweats. Often my hair, which is curly, is escaping from my pony-tail to stick out every direction. My skin is greasy from working in an uncomfortable environment for long time periods without being able to wash my face. There are times when after 18+ hrs in the lab, I have not brushed my teeth. I am everything this woman despises.

Then there are other days when, after pulling an 80-100 hr work week, I am just tired. I ache from having to contort myself in awkward positions and perform repetitive exercises. I actually strained some muscles in my left arm and shoulder from pipetting for 12 hrs a day for several weeks. After all that, I want to be comfortable.  Sweats are comfortable. That's how I roll. I think I've earned it.

And there were several times when I was a newlywed and my husband was deployed when I was so depressed, I was proud of myself for getting it together enough to leave the house and buy groceries. Sweats were as good as it got. It took me several hours to work my way up to even putting them on and leaving the house.

So tell me, in these scenarios and the myriad of others not recounted here, what right does another milspouse have to judge me and put me down for wearing sweats?

I would like to suggest that if you are bent about my attire, make an effort to get to know me. Either you will walk away realizing I am doing the best I can and you should nag someone else, or you will pitch in and help out so that I have time to worry about something as superfluous as fashion.
