To small for lolita?

Im having a hard time fitting into brand lolita pieces that ive bought. Its pretty sad buying a dream dress only to realize its baggy or too big. Do other lolitas have the same prooblem or any advice? My measurements are 32 24 36 and 108 pounds or am i just looking at the wrong brands? I'm into both sweet and gothic Lolita and I am 5'3.
