Brandsfever is my favorite fashion site in Singapore.
I just bought a pair of Jessica Simpson shoes and a Kate Spade handbag. Both items were delivered next day, got the shoes for $19 which normally cost around $130,..
They offer really value for money but not always fast, I also experienced delay, purchased a Desigual dress for $59 last year which took almost 3 weeks to arrive. However 59$ was worth waiting.
They told me that some products are shipped from overseas and some of the products are shipped from Singapore. Check out their delivery times on their website before you order.
