body shop wont let me select athletic cloths for children ?

[ElisiaStarlight]

In body shop it will not let me select Athletic cloths (its greyed out) for kids, both genders.
I wish to make some new athletic clothes, could someone tell me how to fix this ?

You make the clothes like you normally would, and select Everyday. Then you need SimPE and change the category that way. Here's a tutorial. http://www.modthesims.info/showthread.php?t=138073
