I think curvy women are beautiful and sexy.  For reference my definition of curvy would include bodies like Paloma, or Sarah or Riley at RSG.  These women have nice curves on their firm athletic bodies.

For those who know me, you know I never lie, to me curvy means exactly that, curvy. BBW means , (as you say) fat.
If you look at some services descriptions, every girls age is 25. Come on now, really? On sites like back page you can pretty much count on that most of the girls descriptions of curvy to mean they are on the heavier side as well as their age to be older than stated.  

If a girl truly is curvy, no matter what her weight, she will say she is curvy.

I like Jill's take on it...and we have to realize that it is SUCH  a subjective description. (depends on which way the curves are facing i guess) ... I, personally have always used it in more of a chest to waist to hips ratio...description...an "hourglass" if you wish.   As a competitive athlete..I am anything But the typical washboard, lean triathlete..but carry muscle mass and sometimes the curves are more tight than other times...the word "curvy" brings that home to some that focus on the "athletic" (ie" some think "lean, washboard, flat chested runner physique"  however..a 36C-27-36 132-135# IS FAR FROM bbw or fat in my opinion...or even borderline "voluptuous"

What is average anyway. Jill is always spot on with her descriptions. There are guys out there that enjoy different body styles but it is nice to know what to expect so that ones expectations can be met. I know I have read descriptions on this site that state "average" only to be disappointed. Of course it is nice if a girl's web site offers recent and clear pics . I would love to see the description of "fit" or sometimes a better description might be thin but not in shape. I have seen a few younger gals that are thin but have some body fat on their tummy and thighs that shows it is obvious that they do not take good care of themselves, I would rather not be with that girl. The term "baby fat" is ridiculous, what the hell is baby fat in a 28 year old??? perhaps a little more descriptive like in good shape but a meaty butt or thighs. I guess the only way to look at it is a recent pic is best but it would be nice if guys were a little more descriptive in their reviews and TER considered some better terms to describe someone

I personally like "curvy" ladies. To me it is what doctors might call "normal". I don't like supermodel skinny at all.  So a little padding here or there is fine with me.

I just glance at Rosie's pics to get an idea of what you were talking about and I guess I would call her curvy: she's tall, she looks like she has a juicy booty and soft thighs.  I usually associate "curvy" with being hippy or top heavy though and no, not fat.  
When I think of the word curvy I see in my head tight curves, a womanly but fit to reasonably fit body.  "Curvy" is suggests "proportional" and without extremes.

A Sophia Vergara body type which is slender but hippy and top-heavy-to me is curvy, as is the girl in the photo below (and she's probably a good 30-50# heavier).

If it appears the girl is heavy and she's using curvy as a descriptor then it is what it is.

Personally, being a "heavier" provider I can't remember the last time I used the word "curvy" in an ad because I don't think its appropriate for my body type for my personal definition.  
My profile says "Baby Fat" which is IMO a polite way of saying "fat, but not too too fat" lol actually and quite stupid- I think "baby fat" means a skinny fat girl perhaps size 2-6 who is slender but untoned and soft.  
I use "medium-athletic" or "voluptuous" when I have to because though I am full-figured if you thump me I'm not going to ripple.  When men run their hands over my body they "wow, you're so firm".
Putting curvy in an ad can't describe that so I don't bother with it.

Just look at the pictures, they speak for themselves.  If she's calling herself "curvy" and everything is angle posed, there are no tummy shots, there are pictures of her feet and toes or shots of just her eyes in the gallery and she isn't selling domination...chances are she's  heavier than *you* would probably like lol.

So no, I don't always think "curvy" means at best overweight or at worst sloppy fat- there are some providers who use it appropriately and some who don't(just my opinion on that definition but again, if your body is totally out of shape, you have no muscle definition, are not proportionate and are not firm to the touch those aren't classic curves, you're a BBW and that is okay)- but it all boils down to what you're seeing (or aren't seeing) in the photographs.

Jill is brutally honest and some girls that are curvy like Ally seem to be more critical of themselves than the true bbw's and if you like curvy there's really not too much difference unless you wander into obese

Circumlocution: using a word or words to be deliberately vague.  From the same root as "circle," which is (ironically) a . . . well, it's a curvy geometric figure, right?  Personally, if I happen across an ad with the word "curvy" in the caption, I assume it means the lady is either 1) curvy but possibly still thin 2) not thin but a somewhat bigger-figured lady (not a BBW but a BFL!) 3) chubby or 4) a genuine BBW.  Of those four options, three signify a lady who may be great at what she does and delightfully sensual, but who is likely to be bigger than I'd prefer when I'm in the mood for a conventionally sexy and thin companion.  Not a spinner and sporting more than an extra 5 or 10 pounds.  Don't get me wrong: sometimes I feel like nutting with a curvier gal, and sometimes I don't.  Depends whether I'm looking for Mounds or not, you know?  (Couldn't resist.)  But the bigger problem (no pun intended) is that when a lady advertises herself as curvy, I can't help being skeptical; in a personals ad, when the guy or gal writes, "Could stand to lose 10 pounds," we all know that means "Could stand to lose 30 pounds . . . at least!"  Now, I have to reckon that any provider knows that she's going to lose potential clients who prefer Twiggies and spinners when she places an ad with the word "curvy" in it, and the only reason most (not all) providers would bother to include "curvy" in their posting is to be able to tell the fellow who shows up, "Why are you so surprised?  My ad said I was curvy!"  So while I am certainly glad to be in the company of soft, lush ladies with a little extra cushion, I think that the commonly understood usage of "curvy" means "not thin and maybe not fat but possibly fat."  Is that clear, TEResidents?

. . . everyone's above average, right?

I've always thought Marilyn Monroe as the "curvy" type & I describe myself as curvy because... well obviously I have serious curves, yet I am corrected often so I think "curvy" to most people nowadays is more of a plump build. Either way it's still sexy, we likes extra meat to nibble on

Mona has curves!

For me "curvy" implies a "fuller figure" lady, not plump or "fat." Unfortunately, there is no governing body for the hobby which can set rules and regulations and definitions like this. Best way to tell is hopefully lady has some recent photos on her website so at least the gentleman has an idea what to expect.

I think curvy refers to a nice hourglass figure, regardless of weight.  I think some of us, like myself, who aren't the typical 125 lb 'perfect 10' by society's standards, can still consider ourselves CURVY without having to give our weight or some explanation along with it.  

Speaking of that hottie, are there any reviews on Rosie?  I didn't find any in Boston.....

I recently had a similar experience while writing a review for Adriana (was in Boston but based out of Florida). I wrote a rave review of our time together, complete with words like, "Don't miss this one" and "amazing". However, I described her "curvy" body as "thick & tight".
