I really almost heard a "plonk" from dropping my mouth as I was reading this post. Thanx for starting it, Suz! (are you feelin'better?-I hope so:-)).
I never ever could make leggings work on my frame and my wardrobe with panache. But then, I thought I know what tights and leggings are.... Even mounching on Suz's latest definitions, I am rather like Astrid, now. Still clueless.
I know I wear kind of hose(call them nylons, sheers, opaques, patterned/lacey tights) all the way with skirts and dresses(all knee length or longer) in fall, spring and winter and when the weather doesn't allow me bare legs(which I love best, even for dressier outfits).These have mostly a nr. of denier 5-30(max 40!) DEN. Nothing thicker than that is required for my climate, or at least my everyday life, but I also consider anything thicker(and leggings usually ARE thicker) won't look appropiate with my skirts/dresses AND shoes. I guess I am on the dressier side, or just don't get it?
Then, I tried so much with the leggings for tunics. But I have balerina like muscular tighs (as I did many years of classic ballett in my youth). So, my tunic length (which for others is usually midthigh or the mini length) would be exactly the same as my skirts and dresses lengths(around the knee)- so then, why bothering with other than tights, at all. Would have the bounch on the middle, and on my apple belly it's no fun at all.
I now have a good amount of cellulite, too-which is showcasted through a regullar, body con leggings-so not fun either.
Conclusion is, my tunics just cannot end where my thighs are the widest if wearing regullar leggings-or I have to wear much thicker, and not so body con leggings-which are in the end not leggings anymore, rather some ponte skinnies or even better, some straight legs, at least.
Still, I find a leggings with a tunic/dress(call it how you'd like!) having the right length a good(even edgy and/or creative look) on other womens(like Debs, for ex). But saddly, I cannot achieve that decent look for the life of me:-(.
I have to leave now, but will return to read all the comments, so much to think and learn here. Maybe one day...:-)
