They look like they have similar sort of shimmer although SE looks really gross in the bottle. They both have pink/orange shimmer that changes to purple/gold. Very nice.
So here they are with one coat and two coats over Where's The Soiree?
4th picture has got its labels round the wrong way n_n;
Sheer Enchantment - Much less visable than Femme Fatale. It is more glitter like with the size pieces.
Femme Fatal - I love this polish. I wore it over Morgan the other day... those two were made for each-other! Smaller pieces than SE and a lot more of them. I only used one coat of Femme Fatale on ALL pictures.
