Based on reviews, I ordered 3 slips in 3X instead of my usual 2X.  The fabric and the colors are nice.  The sizing was consistent in all 3, but they are cut oddly:  even in 3X they are a bit snug around my hips and very loose under the arms. I can understand the reviewer who said these fit men, as they appear to have been cut straight up and down instead of following female curves.

I got these to go under a couple of 1920s dresses that I'm making, and it will be easy for me to take in the underarms. Also, the straps are skimpy, and 1 is almost coming off (don't know if it'll survive it's first machine washing), so I'm glad that the slips have the ties in back, as I can cut them off and use them as straps instead, since I didn't like the ties to begin with.

Overall, I feel I got a good enough product for the very low price I paid, especially since the fabric is nice.  But if you want something that's better fitting without needing any alterations, you should look at the more expensive slips instead.
