Short Sleeve Denim Button-Up Shirt

This isn't just boxy, oversized. This is Billie Eilish wrap around yourself twice kind of big. I'm reordering in a size down. I am normally a size 12 or Large. I'm going to try a medium because this is the only short chambray short sleeved shirt at a reasonable price that I could find. It's not heavy denim, it's light weight chambray and the fabric looks like it is pictured. Just what I want. I half expect the medium may be too big, in which case I'll take it to a seamstress to cut down to a more reasonable boxy, oversized look as one would expect from Treasure & Bond. Not the extreme runway trend look that was delivered.
