the only singaporean girls ive met are in thailand, ive met 3 or 4 of all ages and they were all beautiful! i love their accent also :D
ive never been to singapore irl tho so cannot say what the ones that dont come to thailand are like
as for smells, can it really be so bad? only bad smelling place ive ever been has been patong in phuket but thats only by the grids
