Lol, I went through this late 2015.
My wife replaced all my chinos and baggies. Everything was too big. Like waaaay too big.
Then I ran out of holes on my belts, so she replaced those (not making new holes).
This all around Nov.
28 Dec I weighed myself to see if I had picked up anything over Christmas. Nope - done 500g. No increase.
My 2 new belts have now run out if holes. On the last. Need to drop another size on the chinos too.
All shirts were replaced early Jan, so all is good there.
Hitting the carbs hard, but low on the sugar. Still struggling to lose a bit of weight on the gut (and it is just a bit - then the 6 pack should start showing

), and from what I just saw in The Sugar Film, the bit of sugar I am still getting is the culprit. So I know what needs to be done. 70's, here I come.
