On Tuesday, breast and ovarian cancer charity Pink Hope held a star-studded launch party for its Bright Pink Lipstick Day fundraiser at cheap prom dresses.

And nobody appeared to show their support for the cause more than Channel V personality Carissa Walford and lifestyle blogger Caroline Groth.

The pair both came to the event decked out in the colour pink, sporting pink hair, lipstick, and clothing.

While other celebrity guests opted to keep the colour confined to their lipstick, Carissa and Caroline rocked the shade proudly from head to toe.

Carissa stunned in a racy lace cocktail dress that showcased every inch of her enviable curves.

The frock's bodice featured sheer lace, revealing a cream bra underneath.

Confident Carissa posed proudly in the ensemble, placing her hands on her hips with a beaming smile on her face.

Meanwhile, the bronzed Caroline went for a more demure look in dresse for prom 2016.

The socialite sported a tight striped sweater dress underneath a powder-pink coat.

She finished the fashionable look off with a pair of creamy pink heels.

Other celebrities at the event included The Bachelor's Anna Heinrich, actress Natalie Bassingthwaighte, and model Tegan Martin.

Pink Hope aims to raise awareness for breast cancer and ovarian cancer.
