Your stock is quite adorable for littlies particularly the kitty cat ones

Mostly sensible advice from other posters IMO

Unless there is something that looks very dodgy (which your ID and listings don't look like all)  I buy from newbie sellers all the time without hesitation, as many others buyers do too. 

I agree with others, coming into Australian summer ain't the best time to be selling those costumes, but you may get some sales in the coming months from those buying to send Christmas pressies overseas
