Victoria Secret - Size help.....

I am going to order these cute robes for my BMs but not sure what size to get.

I always get XS and they are usually still big! MY sisters are around the same size as me except I have a much smaller frame.....They are about 5'4 and 130lbs or so. Should I get them just a regular small?

No - definitely extra small

I'm about 5'7 & 120lbs and x-s is perfect

depends...robes can be a little bigger. it might be better to get the small incase the robes shrink in the dryer.
