Launching this month's promotional effort, Mary Kate and Ashley Olsen splish-splashed around in a kiddie pool for StyleMint’s August T Moment contest.
The former "Full House" stars have invited all those interested to submit a photo or video sticking with the theme of "Show us how you keep cool wearing a T shirt" for a chance to win an entire free year of StyleMint, which includes 12 StyleMint Ts.
With Mary Kate and Ashley set to select the winner at month's end, all submissions can be throw into the competition via the StyleMint Facebook page.
Along with their August T Moment doings, the Olsen twins also have designed a limited edition coin purse under their Olsenboye line at JCPenney.
Available at JCPenney for just $9.99, proceeds from the bag are set to be donated to help underprivileged children through Pennies from Heaven, which funds after-school activities.
Of the cause, Ashley told in a statement, "Every child should have the opportunity to be part of a positive and nurturing environment after school."
