I'm 5'0 inverted triangle/apple. I have a short neck, straight shoulder line, not much definition in my collarbone, C cup, not much of a waist, narrow/boyish hips/butt/thighs. Vertically speaking, I always thought my legs were short then I learned that I am proportioned to the golden ratio, so my legs are neither short or long, they are just right. I am also medium boned.
Advantages:
I look great in V-necks, or anything accentuating the bust. Straight shoulders mean that jackets and cardigans hang nicely and I certainly don't need shoulder pads. Cowl necks, especially exaggerated ones, look good. I have great legs to flaunt. I can rock leggings and skinnies like nobody's business.
I look great in A line dresses that are fitted in the arms and then forgo the waist, while hitting a bit shorter to show off the legs. I can also rock a sheath dress provided it has a V neck and is fitted just right (and forgiving to my waistline).
I can generally play with proportions to my heart's content because my vertical proportions are pretty ideal (golden ratio). I.e., long tunic over leggings works just as well as high waisted with short top. I can do above the knee dresses, midi dresses, or maxi's.
As long as I stick to petites, I have no issues with sleeves or pants that are too long or too short.
Disadvantages:
I absolutely need petites for the vertical proportions. But some petite makers think petite means super slim, and I'm not, except on the bottom half. And being resigned to petites means less choice. Yet I need a higher rise in my pants/jeans (anything less than 9 inches slides right off as I don't have much of a hip shelf to hold them into place). I can sometimes get away with regular jeans for this reason, but then the details like pockets are scaled all wrong.
I look less good in spaghetti or strapless styles. I've got a softness about my upper body that makes crisp button downs just not work, not to mention the gaping issues. I can end up with dreaded uniboob in certain tops. I can wear some crew necks provided they are cut low enough, but it's still not my best look. Forget turtlenecks -- they look awful in general, although there is the rare one that will work, it would be scaled for a short neck. But I generally find them uncomfortable and fussy. Forget any puffed shoulder details, or epaulets, as I look like a linebacker.
My belly and lack of waist is my worst feature, no matter what I weigh. Lower rise pants = instant muffin top. Disguise tactics are necessary here. There are a lot of tops that would look great, if only they weren't too tight in the midsection. Yet if I go with a top that's too voluminous, I just look dumpy.
And when pants or jeans fit my waist comfortably, they are very likely to be too loose in the hips and legs. I do love flowing wide-leg pants but these are difficult to fit as they tend to swamp me and be too wide. Meanwhile cropped pants just look goofy on me for some reason (you'd think it would work for me and show off my small ankles?) -- I hope this trend dies soon!
I have thrown out all my skirts, as they just don't work due to the waist and belly. Dresses with a defined waistline do not work on me at all. I have no hips to fill out a fit-and-flare or skater skirt. Pleats accentuate the belly so forget that.
Jewelry that is scaled right is a challenge, since I'm medium boned yet petite. I have given up on bracelets and watches. Many necklaces have to be altered because they are too long. I love pendants even though they often do the "boob lasso" thing.
Similarly handbags are a challenge as they need to be scaled just so, including the strap. Many handbags are just too big and swamp me.
