This is the first time I'd tried wearing a full control slip (I tried several before I picked this one). I found it not quite firm control, but definitely helpful to smooth out the line of my body under tailored work clothes and provide a little tummy flattening, which is what I wanted it for. It's surprisingly sexy--has a definitely vintage feel, and the seams are well-made--and stays in place quite well. I wore it with straps in place but seems like it would do fine strapless (which I don't usually say, as a 36C). Fit true to size based on bra size for me, and it provides nice shaping without too much padding in the cups. Also, relatively cool to wear all day, and I didn't feel pinched or cut anywhere by the edges. Four stars.

Why minus one? The one thing I just don't get is the way the crotch closes: hook and eye closures, with three rows for adjustable sizing as for a bra, right in the dead middle. THIS IS SO AWKWARD. Why not use snaps? Or perhaps put the closure on the front of the garment where you can, you know, reach it? Undoing and redoing this requires both time and dexterity. I would just cut out the stupid part altogether, except I think without it the skirt would ride up while wearing.
