I recently purchased my dress (pictures attached) and am trying to figure out what to do for a bra.  As you can see, the dress has a VERY low back, making a regular bra out of the question.  Do you think I should try to find a low-back bustier? A stick-on, backless bra? Or do I even need a bra? I'm a 32 C... 
I was considering having the seamstress sew in cups.  If I do that, what should I wear to the fittings? I'll be honest, being completely topless while trying on my dress made me a little uncomfortable.  I would be even more uncomfortable if I was braless while the seamstress was messing around in that area.  
Any thoughts? 
Thanks!
