So I had my final fitting yesterday and the dress fits perfectly - though it felt a little more snug than it did a month ago; I remember thinking "phew, I have some room!" last month, and now that room is gone (my seamstress didn't say anything about making adjustments to the top, so I don't think she changed it). But it's still comfortable.
Not sure if I actually gained any weight over the last month or if I just had too many carbs this week, but if I were to stay the same size from now until October 10th, I'd be golden. My worry is that.. what if I don't? I feel like if I gain any weight, the dress will be too tight.
I don't have any more fittings and am picking up the dress two days before the wedding.
Any suggestions on what to do if it's too tight the day of? I've read something about safety pins and fishing line, but not sure how that works exactly. Below is a pic of the back of the dress on a model for reference.
