HA! Now thats what I call a good dilema!

Yes, as Eno said, stay on your plan, whatever it is!
Maintaining your weight for the first year will be very helpful for your confidence in that you can maintain your weight.

As for all those clothes....I can get away with tops that are a bit too big but bottoms need to fit right.
How do you wear your clothing? Meaning tucked in tops? tunics? knits? Wovens? Layering shirts over tanks?
Have you tried on everything to see what you can alter or belt up?
Bottoms are key and have to fit.

You may need to go through your clothing a few times over the next year as your body settles in.
But I can tell you that now 6.5 yrs later, I have jeans from that first year that still fit but are so worn out that I can't really wear them. I mostly wear jeans due to my work.
