Your mom does not sound like someone who is built like Britney Spears, i.e. very mesomorphic. I am 5'2", muscular and as long as I am working out or even just moderately active 120-125# is very lean and thin on me...a size 2-4 even. Honest. But I do know women my height who look "fat" (not obese exactly) at that weight. Also, Brit is only 25. Don't know how old your mom is but I am assuming she's at least 10 yrs older than this. Once you get past a certain age you pretty much have to work out to keep from losing the muscle mass that is going to keep you looking smaller without having to weigh less. Especially if you are not very mesomorphic in the first place.
