Go to a department store that sells top notch make up products -> you know the ones uhrm 'Army & Navy' etc etc, where you walk in and a barrage of perfume scents waft up your nostrils.
WELLLLL go to the make up counters and ask them about wanting to try certain products but not knowing how to apply them properley, you will probaby get a free make over out of it with top notch products, it hasn't failed yet haha

(I do this about once every month, so the workers don't get too suspicious) and it feels lovely having your make up all profesionally done (for free may I add). Just buy a cheap eyeliner from the make up counters if you feel a bit cheeky ;]
Good luck
