>>> so fashion trends come and go, but there's some rules that never go out of style.

>> like to show some skin above a certain age or how to mix prints.

>> well, there's one guy who knows style, it's this guy. he's the co-host of " fashion police " on e! breaking down the good, the bad and the ugly. also the author of "glams yorous by george." what was the inspiration behind this book, george?

>> well, a lot of it was being on fashion police and every time someone looked fabulous, we would be like she looks like a movie star . we have reality stars that are wearing their dresses too small and heels too high.

>> too shiny.

>> i was trying to go back to the roots of movie stars and glamour. and just, you know, giving women ways to emulate that in all aspects of their life. hair and makeup, entertaining etiquet etiquette.

>> cate blanchett is elegant and graceful. so just kind of bringing it that way and being accessible, as well.

>> let's start with jennifer lopez . you only expose two body parts at once.

>> at the max.

>> jennifer is doing a super, super short skirt, which is a great way to go if you have great legs. woman at any age. we've been seeing sandra bullock and julia roberts doing the same thing. it's a great way to look sexy and elegant.

>> right.

>> and at a certain age, do you start limiting how much you show?

>> yeah. you know, the legs --

>> yeah. the legs are the last to go.

>> the last to go. when you got it, flaunt it.

>> if you can't hide it, decorate it. absolutely.

>> which i told you not to do.

>> that's right.

>> she wanted to wear these earrings. i was like, you don't need them.

>> no, you've got a colorful blouse, take the earrings off.

>> and you're gorgeous.

>> thank you.

>> jessica alba 's a great way of how to mix prints. it's a big trend right now. and what you want to do is mix a larger print with a smaller print and that whey there's --

>> does it matter which top or bottom?

>> no, i don't think it matters.

>> that's hard to know.

>> and keep it in the same color family. to to tones the same.

>> and you say structure your clothing.

>> yes, define the waist. and i've told mindy this at a dinner once. doesn't matter what size you are as long as you have a waist and it's visible and she loved that.

>> yeah. you don't want a big tent . you don't want a shapeless shape.

>> what about this dress?

>> the printed one?

>> a big print is the way to go on a red carpet , as well, because it just stands out more and this a-line fit and flare shape. it's a big look in the late '40s early '50s. a great way to go.

>> finally, tell us about james marsden .

>> i've got to applaud james for being bold . a lot of guys are afraid to do anything outside of the box. it's a bold checkered suit. i think for the, you know, for the guy at home watching it's easier to mix maybe the plaid jacket with the solid pants or vice versa . on james it works because he's a movie star .

>> right.

>> he's a cool guy.

>> carries it off.

>> he's not impeccably dressed as you are, al roker .

>> thank you.

>> putting me to shame.

>> high praise indeed. " fashion police " airs friday at 9:00 pacific on e! or sister network. we're back in a moment. but first this is "today"
