Aurora - I am a DIY bride and my AD in on 30. Co-ordinated & source everything on my own. No helpers.
First of all, you must know what is your budget. If you are not taking any BS package, you can actualy save a lot $$. If $$ is not a matter of concern, get a wedding planner to do everything for you.
Wedding Gown - I bought my WG off the internet and altered to size.
EG - I took one of my old gown and updated it. Or rent. There is a shop in Delfi Orchard 2nd or 3rd floor. Nice EGs.
Suit - D'Zendiq - Far East Shopping Centre (next to Hilton Hotel) $300.00 for MTM suit includes 1 MTM shirt & 2 ties. Cheapest I found with not bad material. No point in renting. Rental is usually just the jacket. Those cheap tailors uses really poor quality material. Tailors in Peninsula - very EX but good material.
Makeup artiste - Sandy Ho 90055210. Very nice & experience lady. Do not overcharge. Contact her for rates.
Photography - I just took my studio & outdoor PS. Contact Andrew Tay 96867894.
Try to book as early as possible. Their schedule quite tight.
Flowers - Can go to any neighbourhood florist to order. Just DON'T tell them it's for wedding. Will be cheaper. Can tell them what you want, how you want it done.
Car - Just borrow from friend, relatives etc or look for car rental company.
Car Decor - Go to Arab Street and buy the mesh kind of fabric and tie. Ribbons, Kin Soon Company(wholesaler of ribbons) also on Arab St. If you want fake flowers, go to nearby Concourse.
