I recommend gel nails.

I usually go around barefoot often, but I feel a little embarrassed about being barefoot in the summer.
So I bought this after getting a recommendation at Olive Young, and it looks refreshing and pretty with a summery vibe.
It is transparent with just one application, so you have to apply it two or three times. I think I will use it a lot this summer.

Olive Young sometimes has a buy-one-get-one-free deal, so give it a try. I highly recommend it.
