Diet vs Boobs

We've all heard women complain that the first place on their body that loses weight is their breasts.  I wouldn't mind if that happened to me as long as I lost weight all over so I'm at least proportioned.  They're kinda big and a pain anyway.

So a few weeks ago, I had to start putting on my bras by using the middle of the three rows in the back.  I was like,

"Huh?  Guess I lost weight around my rib cage.  Maybe I'll luck out and go down a cup size."

Then last week, I had to start putting on my bras by using the tightest of the three rows in the back.  I was like,

"Weird.  Maybe these bras are all stretchy so I can't tell the cup difference."

Then this morning I put on a bra and realized  that it was so loose that it was bra shopping day.  I went to Kohl's, picked up a few bras, tried them on and bought this cute Olga one (below - Kohl's model pictured) along with some more serviceable ones and some underwear that don't look like saggy old lady undies.  Yep.  I lost weight in my butt too.  Some clothes look better, but some like the underwear...  not so flattering.

But...  I just bought a smaller size band.  This diet hates me.  I swear my boobs are bigger.  I bought my normal cup size since I kinda refuse to buy anything in the ridiculous size ranges.

Another weird thing I've noticed lately:  my socks don't fit properly.  I don't think I suffered from fat-foot-syndrome and that I've lost weight in my feet, but what other explanation is there?
