clothing not showing

Hi all.
I have a problem with my av,when i put on a top,most off the time it wont show.
Its not with all the clothing,but most.
Dos anyone know why this is happening and how i can solve it.
For now thanks

You can try taking it off and putting it on again which is a way most people do. Also, try going into appearance as many times this is required to be able to rezz things, including yourself for others to see.
Rebaking, might also help. And try moving to another place as sometimes things don't show or look terrible in certain spots.

Good Luck!
