It and other beautiful bags can be found at www.oioi.com.au
This sachel bag by Isoki is really cool! I think it is pretty trendy, and a really good price ($89) it comes in blue and black as well.
This is the Vera Bradley Baby Bag for $99US, unfortunately you can't get it in Aus, but I am sure you can find someone selling it on ebay that is will to ship it over here. There is a massive variety of the lovely Vera Bradley patterns as well!
If budget wasn't an issue, I think this Storksak Sofia bag is really nice, but I don't feel like spending almost $400US, or even more here in Aus at a whopping $499 .. ouch.
Vanchi also have some really cute bags, and lots of different sizes. This is their Hobo bag. The nice thing about Vanchi is they have really reasonable prices, this is around $175. They also come with a lot of necessary accessories.
And just in case the guys felt left out (although I doubt any of them scrolled down this far), I really like this one for Dads
If you have a nappy bag that you LOVE.. please let me know, because I really don't know how practical these are!! Always looking for more cute bags so I would love to hear your thoughts!
