Let's face it: sets of real Egyptian cotton sheets are few and far between. At least, as far as the level of quality associated with the term. Sure, there are a ton of sheet brands that claim to be made of “Egyptian cotton” and while that's true, they're deliberately misleading consumers into thinking that their product is higher quality than it is.
How do they do this? Well, the truth is that simply being “Egyptian cotton” is nothing special. In fact, most of the cotton produced in Egypt is the same quality cotton as that which is produced in the United States: upland cotton. Only cotton produced in the Nile River basin and is an extra long staple (ELS) cotton is associated with the quality most people think about when they think of “Egyptian cotton”.
Low quality cotton can be grown anywhere that high quality cotton can be grown and this is often the case with Egyptian cotton sheets. You have to be careful when making your purchases and read the labels carefully. A quality product will typically mention that the sheets are “extra long staple cotton” instead of just saying they're “Egyptian”.

Another solid way to tell if you're getting the real thing is if they cost more than regular sheets. You can expect that at minimum, a set of Egyptian cotton sheets will cost over $100-$200, but they can often run more than that. It's not uncommon for a set to be $800 or so.
