image resize, overlaying between different canvas sizes

[waqasp]

Hi all,
i have two images Image A(body image) is on canvas size 1500X2500, Image B(dress) on canvas size 480X720..
i am trying to crop an object from Image B (dress) and overlay on Image A (body image)....i am done with cropping and overlaying...but the problem is after the overlaying is done the object from image B shrink, obviously this is because of the difference in canvas size...
is there a way to solve this problem ?

i am uploading the two images...

if you use photoshop, press ctrl+t and change size of image B or image A.
