Taurillon is the best in term of color saturation, as you know lilac is pastel color, and taurillon leather is to die for, the only negative thing is taurillon leather is the heaviest of the four choices. Next I would pick Vernis, lilac color is so pretty in Vernis, saw it IRL, gorgeous for Easter, and it is so light to carry. Negative thing is you have to watch out for color transfer. Epi lilac is third in line, as Epi is durable, have not seen the Epi lilac IRL but I think it will be nice, and lastly Empreinte, simply because I don't like Lilac color shown in Empreint, so pale to almost light blue to me, not pretty lilac as I imagine.
Is the new lilac epi like the old lilac?
The yellow and pink also looks sweet!!! Are they launched now or April?
