For slips, you might try Sears or maybe JC Penney's. For some reason, they seem like they might stock items like that.
They don't sell slips in department stores anymore? What the... what are you supposed to wear under a skirt? Maybe Victoria's Secret would have them. I'm trying to think if I saw any peripherally at Wal-Mart or Target.
I bought a half-slip at Target last year, and I know I've seen them from time to time at Wal Mart.
Or, definitely try Lady Grace (I think there's one in the TJ Maxx plaza across from the mall.)
I buy mine online at Penney's for just that reason!
is it possible the young lady you spoke to was on crack? did the others ones check, or just believe you? because i am having a hard time buying that story. (the whippersnapper's story. not yours. that's freakin' appalling. curse you macy's!)
enjoy not being the young whippersnapper in this comment, btw. :)
