The girl was hideously enthusiastic to demonstrate. This post shall focus more on makeup than behaviours, as that would better tie in with this post already answered.
The first thing you ought to consider is your hair. AC prefers soft pincurls when attempting a feminine look, a tutorial for which can be found here. Contrast of colouring on the face is considered feminine, as are full lashes and brows. With this in mind we are going to start with a “natural feminine look and the amp it up a little.
Start with foundation to smooth the skin tone. Anything that makes your skin look soft is good.

Brows are important. Keep them soft and full and slightly arched. Going too thin or dark is an instant giveaway. MAC Quite Natural is used.

Blend a brown over the lid and into the socket. Keep it light, but one of the biggest factors of femininity when it comes to make up is a higher contrast between the eyes, lips, and cheeks compared with the rest of the skin.

There are two ways you can apply mascara for a look like this. For very subtle definition apply the mascara from the wand onto a lash comb and then to the lashes. The difference is marked below, eye to the left straight from the wand, eye to the right on a comb.

After evening out the lashes, we added a pick blush along the cheekbone and dabbed plum lipstick onto the lips, just enough to enhance the colour.

You will look more feminine with this sort of makeup, but to really amp it up we are going to make the eyes look larger and the mouth more defined. The idea large eyes are feminine comes from the fact women are generally shorter than men, and thus their eyes look larger and mouths look smaller when they look up. Why that has been deemed attractive I cannot say.
Start by tightlining the upper inner eyelid with black gel and lining the waterline with a concealer pencil. This opens up the eye and makes the lashline look thicker. Tightlining is AC’s most loathed part of makeup application because it makes her eyes water every time.

Other than that we’re going to indulge in quite a thick flick of eyeliner, reminiscent of the 40’s and 50’s, an age when many of our notions of femininity were reforged.

With that in mind we finished with a lick of red lipstick. If you can find anything considered more feminine please tell us.

Stay away from too much contouring especially on the jawline, or trying to redefine your mouth too harshly. Both are very common mistakes. It’s hard to go wrong with a basic French manicure, especially on oval nails. Though squared off nails are fashionable, they are rather hard to pull off in a feminine way. Find the colours that suit you best and wear them. This will soften your skintone are bring light to your face. Hopefully that’s helpful enough.
