Buy something else.

I've purchased two pairs of these because they were so inexpensive. The first pair made it through most of an evening, but ended up in the garbage at the end of the night due to runs. The second pair made it extremely obvious how quite poorly made they are, they didn't even make it through one night. The seams are uneven, they run very easily, and the elastic or whatever is on them to hold them up made me break out badly. Splurge on a nicer pair.
