I love the fit of these... and I can barely tell I'm wearing them!  I used to wear both hi cut and bikini underwear, in other styles, but after trying the hi cut and bikini in this style, the hi cut is all I'll be buying.  In fact, I've already stocked up on them, just in case they end up being discontinued.  I originally wore mainly bikinis due to the lower rise of my jeans (I hate seeing someone's underwear when they bend over) but these are cut low enough that they're not an issue... and they stay up on me (unlike the bikinis)!  Even if someone ends up getting a peek of them, the lace top band is nice.  I rarely wear anything fairly thin, so to date, the no show feature isn't a big deal... but it might be appreciated when I do.

I'm 5'6" and in the 130 pound range (I fluctuate between 126 and 132) and the medium size fits me great!
