Cooling Short Pajamas

I bought these pajamas since they're a non-cotton fabric which is advertised as being cooler than other fabric types. While I don't know if that's actually true, the fabric does have a nice feel. The reason for my 3-start rating is because the pajamas are not as advertised in the pictures and description. For instance, the pictures depict a top that has a reasonable length. In the description, it's stated as 26 inches (size medium). Instead, the top is overly long and falls below one's crotch - I purchased a size small and the top measures approximately 30 inches. The shorts are also a bit longer than shown in the pictures though everyone's body proportions are different. In my case, though I'm just under 5'10" tall, I found the shorts needed to be 2 inches shorter in order to be as shown in the pictures. I wound up returning the pajamas rather than minimally having to pay a tailor $20 or so to shorten the top.
