In the summertime, do and you and your friends go swimming in the lake wearing just cutoffs and t-shirts? For many young people, it doesn't matter what they wear as long as they are there. All that matters is the swimming, and usually it is an all day frolic.
Proper swim wear doesn't hold any special meaning for a lot of kids, right? Even if you forgot to bring a towel you knew that mom would be waiting with a big fluffy one when you arrived home and she would wrap your wrinkly body up just like a burrito.
Well that was then and this is now. Today it seems like a great deal of thought goes into deciding what to take with you to the beach or lake for any occasion. Some will actually accessorize towels and floats to match their bathing suits. This goes way beyond cut offs and t-shirts. These days there are many choices, such as swimwear speedo suits, tankinis, a one or two piece swimsuit and the ever popular bikini swimwear.
The trend is for people to take those large over-sized shirts that were worn over bathing suits for a long time, and adorning them. In fact, some put the belt or tie on the shirt. This is considered swimwear. It can be paired with any suit in case it shouts "summer elegant" so that people be impressed by your style.
