First, I have run a search on this but can't seem to find anything recent enough to fully answer my question: I like my tennis clothes to be loose enough to be able to move easily in and still fit well (a.k.a. make me look good). A tennis shirt for me must have sleeves no longer than half way to a little less than three quarters of the way down my upper arm and must hang no lower than two to three inches below the waist of my shorts. As for shorts, I prefer them to hang to the top of my kneecaps. Yes, I am very picky. I am 5' 8" and athletically built (I'm not in the shape I was playing high school soccer -just one year removed - but I'm working on it. I am however in good tennis shape). I'm not built but I have some definition in my arms, especially my right and I have definition in my chest but again, not anything special. I'm looking for Nike or Adidas apparel and I'm not sure what sizes to order and my local club isn't really stocked in the latest. Help please, I appreicate it.
