I just got this Carry Den from GW Little. I love it and it's airline approved. It was their "Deal of the Day" a few weeks back, for $48......it's still on sale though for a good price! It's not a purse-like carrier but I wasn't sure with dog shows if you wanted something this utilitarian or the more stylish, bag/purse carriers.
