Yesterday was my first alt appt and I was super excited to get to see my dress ( I didn't eat much day of...) I went to the appointment and got into my dress the seamstress began pinning my dress. I said it felt too tight near my ribs and that I felt constricted when breathing. She told me that's normal and that I would be fine ... an hour into the appointment I told her I felt like I was going to pass out and she told me to sit down, she said locking your knees can do this. I took a good deep breath and all the pins bent or popped out! ( I told her it was too tight!). She told me that she will not pin it so tight around the ribs then my mom went to the car to get me a snack, as the appt went on I kept getting dizzier and could only stand for a minute or two before having to sit down. This is apparently common however I am terrified of it happening on my wedding day!!!!!
