Hi Pandora, I have had quite a few blind buys, I just go on recommendations of others and reviews, I know what I like and what I don't. Luckily I haven't picked a dud one yet
Sometimes I think you just have to take the plunge and buy unsniffed as it is too hard to get samples in Australia and Myers, DJs and the like only stock the mainstream stuff, I figure if something is not really me I can always put it on Ebay
I have Lolita Lempicka as well and I love the liquorice/anise notes, it's gorgeous.
If you like the liquorice/ vanilla thing try and get your hands on some Serge Lutens Un Bois Vanille , it is to die for, it is expensive ($150 for a 50 ml bottle) as far as I know you can only get it at Mecca cosmetica but you can order online or find a shop near you but it would, in my opinion, be too overpowering in the warmer months.
