Elation tights

Hellooo! I just bought the Elation ultra high rise tights in the Navy color as a man (I like womens tights better because I find them comfier to wear and more colors to choose from). What will the sizing be like? Should I buy non-ultra high rise tights instead? Whats the fabric like? I heard they were pretty close to the Lululemon Aligns. Thanks :D
