Shopping for luxe in Singapore...tips?

Hi -
Does anyone have any good tips or info on shopping for luxe (Chanel, LV, Gucci) in Sing? Ideally, I'd love to find a vintage or second-hand store.
Any info is appreciated!

Thanks!

There’s this site that tries to be like the Real Real, but I haven’t bought anything before: https://styletribute.com/

Mostly everybody uses Reebonz or Carousell, but there are a few shops that specialize in second-hand premier handbags. Madam Milan has been around the longest, more than 10 years if i’m not wrong.
