Kim Kardashian and Kanye West want to dress their baby in leather trousers.

The reality TV star and her rapper boyfriend already have big plans for their unborn child - who is due in July - and are going to kit the tiny tot out in custom-made ''really fun stuff'' so it can look as fashionable as them.

Speaking on chat show 'Jimmy Kimmel Live!', Kim said: ''If anyone knows Kanye, they just know how into fashion he is, and I think he's going to have things, like, specially made.

''I don't think hand-me-downs are going to work. I think it has to be, like, really fun stuff.''

Asked what fashion-forward items it will be wearing, Kim added: ''Chains... leather pants!''

While the baby was unplanned, Kim confessed that Kanye, 35, is over the moon about becoming a father for the first time.

She said: ''We talked about it, but it was a nice surprise.... He is so excited, it's really cute how excited he is.''

The glamorous 32-year-old brunette also revealed she is scheduled for a scan in a couple of weeks' time and the pair are dying to find out the sex of the baby - presumably so they can get to work designing its super stylish wardrobe.

She grinned: ''I have another week or two. Yes, for sure, I'm really excited to find out.''
