if you're like 155 cm - dun worry - i know a lot of gal friends around that height
i won't consider anyone below average height, unless if they're around 145 to 150 cm


but neways....you could wear shoes that are not too torturing kinda high heel shoes

try wearin shirts that has probably line designs that draws across - from one side to another - when worn on one's body

this would give the effect that you're not that thin

bottom wise - i have no suggestions - basically, pants would do good to cover up those thin areas

hope i've been of help

i'm sure the gals here have much more experience than me

what i'm sharing...is just through observation and through talkin' with gal friends i have

wait, are you like o'er 20 years old or sth?
