Best place to buy swimwear/beachwear for Bali

Please help a couple with picking some floral wear/ beach wear/swimming costumes. Traveling to Bali this weekend.

I have been looking online for some cute swimming costumes and beach wear/floral/vacay dresses - please recommend your fav dresses or swimsuits in Bangalore.

Bonus if you can point to stores in Commercial St or Indiranagar/Marathalli as I will be in that neighborhood today. Thank you!
