Inconsistent Sizing Issues With EpicSports Volleyball Shorts

I bought a pair of Kaepa Low Rise Spandex 3" Shorts Flip Down to get ready for volleyball, but I'm really worried about how big these shorts are. On the website, it says that "measurements may vary slightly," but other words like "material composition may vary" and "logos...placement may vary" make it hard to be sure that these shorts will actually fit right. a volleyball player needs to make sure that their gear fits well so that they can perform well and be comfortable. Sizes that are too big or too small can be distracting and even make it hard to move around during the game. It would be great if Kaepa gave more specific size information or a promise that these closeout changes would not have a big effect on the important things, like fit.
