Believe it or not, there are a lot of people that have a real aversion to wearing underwear. They just can not stand the way they feel under their clothes. They can not stand underwear that rides up and some women hate to wear a bra. They might tell you that it is completely unnecessary to wear underwear and they might be right. There are reasons why most people do wear underwear though.
One reason why is that we were just brought up to wear underwear. The thought of girls running around without underpants used to be just shocking. Many women prefer to not wear underwear underneath their blue jeans and other form fitting pants because of the lines that can sometimes be seen under the fabric. It is not very appealing to look at most of the time, but there are ways around that. Either buy underwear that have legs that do not show so much or many women wear thong underwear. Some women can not stand to wear thongs because of the discomfort. However, blue jeans have dyes in them that can cause irritation and other problems for some women.
The same can be said about men who wear their blue jeans without underwear. Some doctors believe that the dye can be absorbed into the skin of the testicles and could potentially cause problems. Some men like boxers and others will only wear briefs. Both styles are probably equally popular these days. In days gone by, most men wore undershirts, but today many never do. Of course, many business men will still wear them under dress shirts and men who work outdoors often do as well. Some guys just like the comfort they get from wearing a undershirt and nothing else. This is probably how the t-shirt gained such popularity in the nineteen fifties and sixties.
Ladies used to wear corsets and camisoles before the dreaded bra was invented. The corset was strictly for enhancing the figure, but the camisole was a covering for the top portion of the body under the dresses and waist shirts that were worn. After the bra was invented, the camisole was for the most part left by the wayside unless a lady was wearing a thin blouse or dress that required extra coverage. The long slip eventually came into style as well as the half slip. The bra is beneficial to add extra support for the breasts, especially for full figured women.
Under wear definitely serves distinctive purposes and most people own at least some pieces. Today it is not uncommon to see girls with their bra straps showing or boys with the tops of their boxers showing. It is weird fashion statement, but to each generation their own.
