I bought my flightsuit from petco.com. It came with the suit, leash, and a pack of the liners. (you can just use those round makeup applicators for liners though). So far, not much luck convincing River to like the suit, but I'm working on it.
I buy all of my flight suits from Wanda'sCritters.com..............she has amazing customer service and fast shipment....make sure you get the leash too, she offers them seperate from the suits and with....my favorite is the little tux suit. Have fun shopping.
