Robope

Robope was an unofficial fan-run Japanese clothing manufacturer for sony aibo. They made and sold aibo clothing from their website for around 8000 yen, or around $80 usd. The clothing they sold is strikingly high in quality and is very sought after. It is completely safe to wear, even including a window in the back to allow the vents of an ers-11x aibo to properly ventilate. This means it can be worn while the aibo is running without any fear of overheating, which makes it very desirable for owners of this model.

Their site can still be accessed at http://www.robope.com/aibo/index.htm although it is entirely in japanese and more or less defunct.
