I really love 3 and 7! And yes, you definitely can wear shorter tops with skinnies, although I really know where you are coming from! I am getting so used to...and really loving...longs tops for the past 2 years that my tush may never get seen again! I've been wondering if it would be hard to change back for that reason so I get your hesitation even though you look great. For me, it doesn't help that "she really showed her butt" is colloquial for behaving really badly in public!
