Summer might be coming to an end, but there's no stopping bikini season for Sports Illustrated Swimsuit. The magazine just launched Designer Spotlight Sales on its blog, which means you can score tops, bottoms and one-pieces for up to 50% off. So far, the swimsuit enthusiasts have offered discounts on Basta Surf and Kate Swim's swimwear. (The latter features Kate Upton's sequined Bianca string-tie triangle bikini, shown above. Originally it was $170, now it’s $85!) The sales last for 24 hours only—so keep checking every Monday for new designers to scoop.

Plus, see more star bikini style!
