Hi Minda! I might have some good news for you. I spoke to my friend who is visiting Singapore and she just came back from the new Bottega boutique at the Duty Free Store in the City (NOT at the airport) and she said there were quite a number of 30% off nice SALE things left INCLUDING the medium Corallo Veneta that I think you're looking for!
There were at least two medium Corallo Venetas left and one medium veneta that was either blonde or pergamena.
She also said there was one gorgeous bright blue cocker on SALE also at 30% off. The color was described as very stunning and striking with tinges of turquoise.
She was literally at the store just a few hours ago (heard the BV boutique at the DFS in town just opened a few weeks ago).
So if you hurry over tomorrow, you should still find those items on the shelf.
Best of luck!!
