Is It Normal To Try On Your Dress Several Times...

Okay, I promise this is my last post for the day (I hope)! Long story short, I want to go back on and try my dress on before I decide on a veil and hair piece. When I was deciding on a dress, I tried the dress on twice and even came back in after ordering it with my mother a month later to try it on and show her. The dress just arrived a couple weeks ago and I tried it on right when it came in. I was kind of overwhelmed and too concerned with my weight gain to even comprehend all of it. Now I'm in the process of trying to find a veil and hairpiece before my 2nd hair and makeup trial and I want to know if they would find it annoying if I came in 2 weeks later to try on the dress with some other veil options from their store. My first alterations appointment is coming up the beginning of February, however, I need to decide on accessories before that date. I always tell them they don't need to be by my side and that I just want to come in and try it on, but not sure? I always ask to come during a slow time so I wont be interrupting any other brides - it isn't a huge bridal boutique and never busy when I'm there (it isn't like David's or Kleinfeld).
