My wife claims to be 5'10" but I think she is 5'9.5"

Anyways ... size 4-6 and 145-150 lbs is the range of size and weight.

The lowest weight I've ever been as an adult was 135 and I couldn't get into anything smaller than about an 8. It was far too low a weight for me, my comfortable weight in my younger days was around 155-165 and I'd wear a size 12 in a top (wide shoulders) and 10 in a skirt.

I chimed in on this a couple of years ago when it started but I'm gonna chime in again.

It will really be based on your body composition. if you are lean with muscle mass you will hit that range at a higher weight, but if you have less muscle mass than you will have to strive for a lower weight to enter those sizes. So make sure to get your strength training in!!!

I'm somewhere between 5'9" and 5'10" and fit into most size 6s comfortably at my current weight of ~148 lbs.
I am also a teenager and do not carry a lot of excess weight in my torso or legs these days.

I'm not nearly that tall. Oh well.

I would forget being stuck on a "size", and focus on being healthy.

Sizes come and go and are so erratic, it's not a good measure of being healthy and happy.

At 139-143 I'm a size 6 in pants, small in shirts, and size 2- 4 in dresses.

I am a little over 5'9, currently weigh 145 (I do have a fair amount of muscle mass) and I wear mostly 8s and 6s.

I'm 5'9 and apple-shaped, so I have no butt or hips because I carry my extra weight in my gut. So my pants sizes are always smaller in comparison to my shirt sizes. Even though I'm a comfortable size 8 jeans right now, I still wear large shirts to hide my gut. A medium shirt would make my stomach bump obvious.

size 15 - 216lbs
size 13 - 190lbs
size 12 - 170lbs
size 10 - 165lbs
size 8 - 159lbs, fit into a tight size 6 right now.
size 6 - ???

I really have no idea what my ideal size should be anymore. Every time I think I've got it figured out, I drop another size. The last 20lbs before you reach your ideal weight makes the pants-o-meter go crazy because you finally start rapidly losing inches in the gut or hips.
