It's not so much the jump between "Large" and "Extra Large," though that is part of it. The main problem is that things don't fit under the arms. A so-called "Extra Large" can fit everywhere else, except under the arms. And, if something is too tight under the arms, I'll be worried (by the end of the day) that I'm having a heart attack. It causes a dull ache up and down my arms, particularly the left. Don't tell anyone, but I think I'm fatter on that side.
So, considering my budget, and the fact that I really don't care as long as the naughty bits are covered (and the saggy arms), I was off to Wally World to find something that actually fits.
Well, Dearly Beloved, what actually fits looks like maternity clothes! The only saving grace is that modern maternity clothes don't look like maternity clothes. As a matter of fact, there appears to be no such thing as maternity clothes any more. Everything we wear is so stretchy that the tops just stretch further to cover a baby bump and the pants just roll down below it.
Back in the days of Queen Victoria, women stayed home from the time their pregnancies began to show until after the birth. In the years before that, women wore their regular clothes...they just fit a bit differently, that's all. There are countless ancient folk songs along the lines of, "When I wore my apron low, I could not keep you from my door; now I wear my apron high, I never see you passing by."
In the 40s and 50s, the object was to disguise the fact that one was pregnant. The adaptations were sort of ludicrous; skirts with large holes cut out of the front, worn with tops that came well below the hips and were cut like tents. By the 70s, we were proud of our lumps, and the clothes reflected this. The trend has continued, through the overalls of the 80s to the spandex of today.
Fat lady clothes look much like the maternity clothes of twenty years ago. T-shirts gathered a little in the front, cut a bit larger under the arms and a bit longer at the hips.
I still miss my waist.
