@ciao_bella Lots of good advice here, but I will chime in because it's my favorite thing to do.
My eye makeup. Not chiming in!
You can still use any liner that you like, but you may have to do a bit more work.
If you like liquid eyeliner, apply it like you regularly would, but then smooth it with your angled liner brush. You don't have to soften it. You can, but you can also just lightly smooth out any "skips". The same thing with your pencils that don't apply as smoothly.
The best eyeliner that I use is my Laura Mercier Caviar Stick with an angled brush. For me, the Caviar Stictk is the most perfect consistency. It is smooth. Fully pigmented. I can apply it in one smooth line & once it sets it doesn't move or flake. They are beautiful. They are a bit expensive, but I collect any new colors when I get a good sale.
Cocoa is perfect.
There are inexpenive options, too. I just bought several (They had such pretty colors!) Nyx Epic Wear Liner sticks. I was looking for a nice, natural taupe eyeliner, but ended up with purples, pinks & greens! They are very nice & definitely worth trying.
I did find the perfect taupe that I was looking for & it was only $8.99.
Maybelline Tattoo Studio Smokey Gel Pencil in Smokey Grey. It applies easily, is fully pigmented & wears great all day.
I use a Loew Cornell Shader 1/4" angled brush that is $4.99 on Amazon. It's a great liner brush.
I hope you find something from everyone's advice that works for you!
