I bought my dress from I Do Too Bridal and while I was there trying on dresses I tried them all on w/ the crinoline. When it came time to buy my dress and the crinoline I decided that I hated the one they offered. The area where the tool was attached to the skirt part picked my legs repeatedly and I knew it would drive me nuts in about 5 minutes.
So, when I went to Bella Alts to have my dress alts done, I asked her where I could get another crinoline (since I Do Too only carried the one brand). And, Angela told me that I didn't even need the crinoline w/ my dress. I heard the opposite from I Do Too, they said I needed a med/full crinoline or the dress wouldn't lay right.
I trusted Angela's advice (she gets superb reviews here on TK), and turns out, my dress looks beautiful w/o the crinoline.
My TL;DR description brings me to: ARE YOU WEARING CRINOLINE? WHY OR WHY NOT?
