Thanks to all my fellow peevish folk for these observations.
Some reactions:
JK - if I had to unbutton sailor jeans, I would never ever wear them. I can only guess they went for convenience with the zipper, but I can see how it would add a lot of bulk.
LJP - not sure about the actual purpose of the cotton gusset (thanks for the correct word!) but I do find that multiple waistbands and all the layers that accumulate around your midsection when you're dressing for cold weather is unpleasant.
When I was working, I remember days when there were underdrawers, tights, a skirt, the base of a long stretchy camisole, a HeatTech, and then whatever was on top. Too much!
Sally, Zaeobi and others suggesting sewn-pocket reform: I had this issue yesterday, when I wore this jacket. The flaps appear to be merely decorative, but I'm not sure.
This is probably less about clothing than about online retail photography, but I intensely dislike when a garment is only shown with the sleeves pushed up to the elbows. Retailers usually tell you the sleeve length in the text, but not always.
The second one I object to is when a garment's color is given a less-than-clear name. Midnight - is it black or very deep blue? Fog - you'd think that would mean gray, but sometimes it's a pale silvery lavender.
I love how Uniqlo does this (or used to) - if they have 6 different green Heattechs, each one is just labeled "green."
