Ivanka Trump‘s surfing enough this week to consider going pro … ’cause she was back out in the ocean off the coast of Costa Rica, sporting another bikini.

The First Daughter hit the beach with a few pals … walking into the crisp ocean blue with her board under her arm — ready to carve up a few waves.

IT’s wearing a small black two-piece bikini this time around … a lot like the orange number she wore earlier in the week during her beach afternoon with her model sister-in-law, Karlie Kloss.

Trump showed great form with her paddle out … making it over the crest of the crashing waves.

As you know … Ivanka and her husband, Jared Kushner, have been down in Costa Rica for at least a week now — and, Ivanka’s spent pretty much everyday surfing off the coast of the Central American country.

Ivanka showed off her backside in a tight one-piece that was riding up when she went the first time … drawing as many eyes as her solid form atop the board did.

Like we’ve noted before … there doesn’t seem to be any Secret Service around Ivanka — though as President Donald Trump‘s daughter, she does receive SS protection.
