Fit: Runs slightly small

Great Bikini!
This is a great bikini with enough support to hold in your tush just the right amount but with no visible panty lines. I wore Body by Victoria bikini panties for years until their design was changed so much they were no longer comfortable, had too low a rise, and showed VPL when worn under jeans and most clothes. The B Smooth bikini is a smooth, comfortable yet stylish panty. It runs a teeny bit small and while I ordered my regular size which is a Medium if you are in between sizes I would recommend going up a size.

Ridiculously Tiny
Purchased these in a size L per the size chart (L being a typical 12/14) - I was looking for slightly oversized panties to wear to bed. They are comically tiny...like they would probably barely fit a size 2. I'm not exaggerating either, I actually checked to see if I'd accidentally ordered a junior's or kid's product. These are going back.

Tiny! Small. RUNS SMALL. Very small
Purchased for my wife. I wouldn't normally write a review of women's underwear but I think you should know these run SMALL. The quality seems pretty good. But the size seems really small to me. The pink ones on the left in the picture are also a size small, what i think is a fairly typical size small for women's bikini underwear. Do you have a 21 inch waist? Yes? Then a size small might be for you. They are 10 inches across and only 6 inches from top to bottom.

High quality, runs small
Recently bought several pairs of these in size S to replace some old ones I'd purchased more than 5 years ago. Exact same model # and size, but the new ones were so much smaller! (See my photo with the new ones on top.) Granted, the old ones have probably stretched out over the years, but the new ones were uncomfortably tight around my thighs and left deep red lines in my skin; I don't remember the old ones doing that even when they were new. I have 37" hips and wear size S in most brands, but I had to return these and get size M. Even the M is pretty snug, but it's comfortable and I like that it stays in place all day and never needs to be adjusted. My old pairs lasted several years before needing to be replaced. Overall high quality underwear that runs small.

Something has changed!
I've worn the "B Smooth" Bikini for several years now, and have reordered multiple times in the past. The fabric has changed, but I'm not sure when the change occurred, as it's been about a year since my last order. The fabric content appears to be the same, based on the percentages on the tags. But this new version is noticeably more lightweight -- so while the percentages may be the same, the total amount of fabric is definitely less. The new version is not nearly as elastic or supportive as the old version! I suspect the less substantial weight also means they will wear out faster -- but I haven't had them long enough to say. They're still comfortable, and it's a great cut, with wide waistband, but I might have to look for a new panty! Also, I'm a size Small (4-6), but I wear aMmedium in the "B Smooth". They run slightly small.

Raises my flabby old fanny to new heights
These underwear are just great: heavy fabric (so you know they'll last), no waistband (so they won't roll over or cut you off) and a nice little seam up the fanny that...shall we say lifts. And separates. All this in an uber-comfortable package that washes up well and dries quickly. What's not to like? Plus, with the Buy-3 Discount, the price is actually cheaper than a similar, low-rent version I saw in Target. My only - very minor - quibble is that they do, indeed, run a little small. I always wear a L in Wacoal, but found these were more comfortable in an XL.

Most Comfortable and Best Fitting Undies
These are super comfortable. They come up a little higher on me than they do on the model in the photo which I prefer. They are soft and stretchy. They cover the outer part of your lower bum where many others taper down to a V that never stays in place. I highly recommend, but you must size up 1 or 2 sizes. I threw away all of my other brands and ordered more of these.
