My Mothers Group bought me an OiOi nappy bag and it's gorgeous, big enough for both girls things, easy to clean and it doesn't LOOK like a nappy bag.
It's not one of the leather ones but a friend has one and she can't fault it, says it's the best money she's spent on a bag EVER and she has a MAJOR bag fetish...

If it's what you want, you have the $$ then i can't see an issue, we all have things we pay top $$ for that someone else wouldn't.
