I found that the kenzo flower is absolutley spot on,which to me is amazing. Givenchy dahlia noir is also close.
Agent Provaceur really good but the drydown is slightly off to the real thing. On a whim l had Catchment, their version of Tom Ford Black orchid as l hadn't smelt it,but testing it with the real thing the perfume hits with the chocolate note,whereas Catchment has a fruitier top note first but to me quite close in scent. So far the ones l have listed are oils in 3ml so very reasonable for their price. l bought their version of creeds virgin island water in oil and spray,spray not keen on but the oil is more successful but in relation it is reminiscent but not quite right. i like their version of Happy by Clinique,whether it is close or not I can,t remember,but it is light so repeat sprays are needed.
I personally prefer the oils and lovely to carry around, perfume parlour do their own mixes but I've not tried those.
I really liked these oils and happy to keep buying them on occasion
