TIFU by being so pregnant I couldn't perceive what I was wearing before I went in front of an audience

This just happened a couple of hours ago. I am 8 months pregnant and huge. So I am in the choir at my church, and we were singing a special Christmas song, so everyone was supposed to dress festively. I also had to sing a solo before the message, which I was very nervous for.

I picked out a nice red maternity dress with beading on the collar and wore black tights with black velvet kitten heels. I even painted my nails to match.

The first service went smoothly... but when I got home, I noticed I had prominent armpit sweat showing on my dress. Great, that’s probably what everyone was staring at during my solo, lol. So I was determined to prevent this from happening in the second service an hour later. I took off the dress, dried it off, and changed into some pajamas to have breakfast. I also put on an undershirt and stuffed a bunch of tissues under my arms so I wouldn’t sweat next time.

Before I knew it, I was running a bit behind, so I put my dress and shoes back on and hustled out the door. I got to the church a minute before the service started and rushed out of my car. Someone asked if it was too windy for me. We’re in South Florida, so I had no idea what they were talking about and continued rushing for the doors.

Unfortunately, the service began a moment earlier and the choir was already on stage. I grabbed my songbook and lumbered onto the stage from the middle aisle, to my place front and center with the other sopranos. Everyone smiled at me awkwardly, which I figured was due to my tardiness.

We started with a hymn... That’s when I realized I felt too much fabric around my legs for the kind of dress I was wearing. I worried that the tissues from my arms had fallen and people could see them stuck to my tights or something. I could not see past my belly easily, so I leaned over to check, as conspicuous as it was to do so...

The sight and accompanying horror took a moment to register. There they were, my pink and teal flamingo print pajama pants. Still on my legs. And the whole audience sees them. How the freak did I not notice, and how did I get on stage without anyone telling me?!?

I rushed off the stage mid-song and took the offending pants off in the bathroom, then waddled back up to my spot. I couldn’t even run off afterwards and hide, because I had to sing a solo immediately after that! On the bright side, my stage fright for that was gone...

TLDR: Changed clothes in a hurry between performances at church. Unintentionally sang on stage wearing flamingo pajama pants because I’m huge and can’t see my legs.
