would you say she was to skinny?

Yes, why don't you show us a picture of the mysterious shopper.

Depends on her body composition.

I agree that I can't answer your question without seeing this girl. She could be that height and weight and be very toned and fit looking or she could be that weight and look like skin and bones. You're asking people to judge based on numbers and one thing I've learned from adopting a healthier lifestyle is that numbers never give the whole picture--weight, BMI, body fat % are all vague guidelines, not absolute measures of fitness.

so imagine you are walking in a store and you see a girl around 18. She is 5 feet 9 inches and weighs 128. She carries her weight all evenly. She has a small to mediumish body build. if it helps you picture her she has straight brown hair and blue eyes. Her waist is exactly 23 inches. Would you say she is too thin?

I dont know. Im 5'2 and i weigh like 100 so would that make ME too thin....just depends on the person...some people carry their weigh better than others.

the point is not the fact that she is a shopper. its just a random girl you see in your local walmart, your doctors office, the snow cone stand, the park down the road, its not me im just asking if you think that that is too skinny.

Okay, the mysterious girl then. The point is that we can't tell unless we actually see her.

I'm 5'9 and if *I* were 128, then yes, I'd be too skinny. But I also have a medium to large frame, where I think I'd be good at 150-160. Or maybe I see no point in being a size 0 to 4. I'd be happy at an 8.

Like others said, it depends on body composition. However, at 128 and 5'9 I think that could be pretty borderline with a healthy ratio of body % and muscle.

That being said, I don't think that a girl with the stats you gave are necessarily that outlandish. Heidi Klum is 5'9 and 120. She doesn't seem sickly skinny.

thats because heidi klum is always preggers haha =P

Shoot...that probably is her day-before-Csection-and-tummytuck weight.

CAT DEELY host of "So You Think You Can Dance?" is right at those statistics.

I'm 5'9 and currently weigh 155.. I don't ever think I'd hit 128, mainly because I don't think I would look good at that weight.

The lowest I'd prob. go is 140.. and even that may be too thin for me.

Loaded question...everyone carries weight differently. I am 5'7" and look ill at 120 pounds. For other people the same height, they look great. There is no way of saying if someone is too skinny by just reading their stats.

I am pleased to see the generally sensible tone of these responses. Earlier in the year, the tone seemed to be different here-anyone reporting those statistics would have been told repeatedly that she had an eating disorder or was unhealthy.

And the responses are correct--height/weight numbers, by themselves are meaningless. I see this every day. In fact, I don't need a "hypothetical" case. I once worked with a woman who was 5'9", 118 pounds and 27% body fat. She had a tiny frame from the waist up, but did not look unnaturally thin at all. Needless to say, someone like that you tell to hit the weight room, not the salad bar, but she was not "underweight"--not even close.

I also had a situation earlier in the year where I just happened to assess 3 women who were all 5'4" tall and roughly the same age within a 2-week period. Because of different frame sizes, their "ideal" weights (at 25% body fat) fell in a range of 40-50lbs.

she has the same BMI as me, and im not too skinny, and im much older. Id say it probably looks fine, especially at 18

That is impossible to determine by just knowing her stats.

I know a girl who was naturally thin no matter what she ate or what she did. Her bones weren't showing or anything she looked very healthy, but she was just very thin. Looked great, and she actually didn't want to be so thin. Now that she's gotten older, she's filled out ever so slightly and feels much better, even though she still is and probably always will be a slender girl.

I'd need to see her first...see how and what she eats, how much exercise she gets, etc. I wouldn't necessarily care how "thin" she was as long as she was healthy. You can be very thin, yet lean and healthy.

but would anyone really care about whether a random girl in a supermarket was in optimum health or not or what their diet was like??

I cant imagine giving a stranger in a supermarket any more than a passing thought
