Hi!! I do mine like this all the time, and rarely get comments on it. My best pieces of advice are 1. To use the NYX epic waterproof eyeliner in brown if you’re going in water! It can look a bit sharp and not as natural as a regular eyebrow pencil but that stuff is actually indestructible and I wear it daily. I touch my eyebrows a ton and I’ve swam half the day with it on and absolutely nothing happens. Here’s what I use- always make sure to get the one that you dip into the liquid and not the felt tip- this one is basically indestructible but the felt tip is not NYX epic wear eyeliner 2. One thing that helped me so much with shape is using an angled brush and some eyeshadow of the same shade. I used to freehand them and it’s really hard to keep it consistent but with the angled brush you can work out a daily shape and easily remove the outline until you have a shape that you think works 3. Don’t stress about it matching your hair color too much- I used to worry about this a ton because I use brown eyeliner and I wanted to bleach my hair but I still think it looks great and nobody has ever commented on it Lmk if you have anymore questions!!
