It’s a broiling Saturday afternoon and you’re lying on the couch in your panties watching Murder, She Wrote reruns. Maybe you think that’s sexy.

You’re wrong. Drinking coffee in a busted-up pair of Vicky’s is a lot of things. Hot isn’t one of them.

So get thee to Coeur, Philly’s home to Kristina Ti couture underwear. These skivvies are unabashedly seductive — but not in a Frederick’s of Hollywood kinda way. (You’ll choke to death on all those feathers, dear.) Rather, Ti’s collection is stuff you’d wear while padding around the house or to tease some romance back into a relationship.

Garments come in a range of styles, from innocent bloomer shorts and camis to inviting adult onesies and rompers.

So go snag a set.

Come next Saturday, Angela Lansbury’s got another case. But you can be the woman of mystery.
