Is there such a thing as warm pajamas that are sexy for a woman to wear? I mean if it gets down to 60F at night, very few women are going to be wearing that sheer teddy you bought her…
try here! 
My sexy warm pajamas have penguins in toques on them.
No, really. They ARE sexy. Just ask my husband.
Those are SO not sexy!
Well, the women are hot, but they’re dressed in clown suits.
When my girlfriend wears men, flannel pajama bottoms and a t-shirt, I wanna tear them off of her. Rowr!
As a male, I’d vote on this one from that Victoria’s Secret link (though those patterns and colors are stupid.) Any more clothes than that and sexiness is probably out of the window.
My penguins are hatless, but the general idea is the same. Cartoon sexiness, oh yeah. 
The trick is to get a heated mattress pad. Then you can sleep nekkid all winter and not worry about a thing. Well, keep a huge fluffy robe and slippers by the bed, because getting out of the warm bed in the morning won’t be any fun.
Sixty degrees Fahrenheit? That’s still warm enough to sleep naked.
You might want to look into some full-length gowns. Like this, but longer, though that looks warmer than a sheer nightie. Or this.
That’s assuming you’re going for “special occasion” sexy, not walking around in one of his shirts sexy.
I’ve been told my brushed cotton yoga pants & one of those thin tissue t-shirts from Banana Republic are kinda hot 
VCNJ~
Do you have a good one you recommend? We got one and the durn thing was so “safe” it didn’t get warm at all!
I’m wondering about your guys’ definition of warm pjs. I’d freeze my butt off in those things. Some of them are sexy however. But little teeny tiny tank tops and flimsy bottoms are not warm.
Flannel PJs are sexy.
Although, actually, it’s the woman who’s sexy. Especially if she’s warm and happy.
I rest my case.
Disclaimer: I’m one of those loons who thinks headscarves can be extremely sexy, and who thinks frills often aren’t.
I can’t think of any pajamas that are warm, really. Even flannel pajamas are still barely thicker than a t-shirt. For the most part, outside of sleeping with a sweater on or keeping a robe by the bed, there is no real answer to the OP besides anything more than lingerie. All you can hope to do with pajamas of any sort is to block direct exposure to air so you don’t get windchill factor as you move about the house. But if you cover all your skin…
Leopard print polar fleece jammies. Hubby can’t keep his hands off them. 'Nuff said. 
Check out Wintersilks. Those light, clingy silk nightshirts and gowns are toasty warm and silky (being silk and all). There are also some great silk long underwear usually available at Sierra Trading Post for something like $17 per piece. I have it on pretty reliable authority that the black ones are irresistable. For something a little more texturally daring, I have a couple of pairs of cashmere (knit like a sweater) pajama pants that elicit plenty of attention.
Years ago one catalog for adult wear featured something called the “snuggle bunny sleeper”. It was a one-piece jumpsuit type pajama made of flannel. The salient feature was that it had a double-ended zipper running from the top front all the way down under the crotch and up to the small of the back. Combined warmth and accessibility admirably. I’m surprised they don’t still make them.
WinterSilks makes a long bedress thing, which sinces it is made out of thick silk is warm. It also feels sexy and clings to all the rights places in the best ways, and if it’s cold, the nipple action is very obvious.
That plus a pair of slippers or socks and you’re warm enough.
You could always go for the leather catsuit (ala Underworld, The Matrix, etc)
Defitely sexy, and I’m guessing fairly warm.

Nah. Too chafe-y.
Straight leg long pants (think Karate) are super sexy.
and, of course, men’s pajamas are hot.
