General

I gained 40 pounds and then lost most of it.

Now I am in the process of putting some (or all) of it back on

For those who have gained, lost, and gained again do you find the weight returns in the same places or can it distribute differently?

It was the opposite for me. I was all belly for a long time and so I had to adjust my goal weight until I got a double chin and boobs and the other fun stuff.

I did find that regaining gave me bigger boobs and a slightly softer feel.

After going from 180+ lbs to 90 lbs (due to an eating disorder 10 years ago) back up to 140 lbs (I've involuntarily gained 20 lbs since October), I notice a difference in fat distribution.

As expected my limbs (which used to be the fattest parts of my body) is where most of the fat came back, but I noticed a lot of fat accumulated on my lower back, my midsection is thicker with more belly fat (probably due to premenopause) and my boobs are larger (not a positive for me as I don't identify as a woman).
