If you don't have sheer nail polish on-hand, Elle suggested creating your own. "Jelly nails can be made with clear nail polish and just a few drops of colour of choice," she said. "Start out with a bottle of the clear polish and add drops of colour until you get the 'transparency' of the colour. Once the desired colouring is reached, paint your nails as you normally would."
If you wanted a mismatched version of the look that uses different hues on each nail, Elle said you will need a new bottle of clear nail polish (like the Sinful Colours Nail Polish in Clear Coat ($2)) for each new colour you're creating.
