I've seen the news about Pippa wearing leggings as pants... ha ha ha! And http://www.thesellingvalley.com/2012-women-sexy-leggings-faux-lace-skinny-pants-p-243.html skinny pants it makes me wonder - for example, J Crew's Pixie pants - in the J Crew picture, they are being worn as pants and they are called pants - but I have a pair of leggings made of the same material/same thickness.... http://www.thesellingvalley.com/2012-women-kearo-rains-design-sweet-tight-pants-p-242.html leggings for pants leggings as pantsso how is wearing the Pixie pants (as pants, say without covering your butt) any different than wearing leggings as pants?
And which brings me to a second question, is the "rule" different for work out clothes? Whenever I wear my Lulu wunder under leggings (full length) to pilates I FEEL like I should be covering my butt from http://www.thesellingvalley.com .
