As if we needed another reason to put our Amazon Prime membership to use, the enormous everything retailer has added Savage X Fenty to its long list of merchandise. The announcement, which includes the lingerie brand's latest collection, comes ahead of Rihanna's fashion show, which will stream exclusively for Prime members on September 20.

From thongs to bras to sexy loungewear, fall is proving to be a good one for the undergarment lovers among us. Shop the collection ahead.

Thongs sometimes have a tricky reputation, but this will change your mind. The high-waist panty has no back coverage to show off your bum. With bonded microfiber at waist and leg and a breathable cotton jersey liner, this patterned number is everything we could ever want.
