I am a very full girl and i read  a lot of reviews about people getting this dress loving it and it is no lie. I run a 14 us and ordered a large. Put it on the instant I got it (( last night)) Love it!! I will probably purchase a one piece/strapless bra but it was so sweet!! Twirled around in it for 30 min before my husband asked me to stop for fear of hurting myself. Lol. you do not need more tooling it comes with a little of it's own. I will be getting more of these dresses!!
