Worried that I’m not going to fit my dress.

So I’ve been one of those people all my life that have never had to worry about my weight. In fact here for the past year id been struggling to gain some weight.

Just this February I’d made the final payment on my wedding dress the fit perfectly 👌🏻 but just as soon as I do that I suddenly start gaining weight. Not too much, but just enough to make my dress tight on my ribs. I’m afraid if I gain any more that I wont be able to fit it at all! 😭😢

I’ve never dealt with this before and am extremely frustrated as to why my body chose this time to start gaining weight ☹️

Also, not sure if this was the right board to post on, but I figured it’d be good enough.
