Notes on fashion

How to explain the periodic appearance of long-sleeved sheer T-shirts in the world? Yes, they look fine when one buys a "layering piece" to put underneath it, e.g. a basic white tank top. But basic white tank tops are also useful when paired with articles of clothing other than the aforementioned sheer T-shirt. So, inevitably, there will be days when one is tempted to wear the sheer T-shirt by its lonesome but realizes that there are no suitable clean layering pieces in the drawer. Long-sleeved T-shirts of fabric of normal thickness notably don't have this drawback. Given that, why does anyone persist in buying the sheer kind? It's doubly annoying to number among the unsuspecting who think "Ah ha! Cute shirt on sale!" and then realize, no, that its sheerness makes it vastly limited for wear and un-buyable.  Gah.

Also: how am I to understand the tall boots worn over jeans or leggings trend? It seems aesthetically appealing enough. It conjures up nice images of people in equestrian dress. I can support that. But where should I be looking for boots that are suitable for this purpose? The good ones all run expensive, and I don't want to sink a lot of money into some I'm unlikely to wear regularly. And I fear cheap ones would just be uncomfortable in all the wrong ways.
