How do I politely ask this?

I really don’t want any clothes as baby gifts. I like to pick them out myself especially since I’m having a boy and don’t really like a lot of the options for them. I’ve also already bought a lot of the clothes he’ll need.

I’m planning a registry but i know how my family is and they’ll all just go rogue and get whatever they want. Is it rude to ask that no one buy me clothes?

Of course I know that gifts are not mandatory and they’re doing it out of the kindness of their heart but personally when I buy gifts i want it to be something useful.
