Worried About Dress Tearing on Dance Floor?! Help

I have a fitted wedding dress that is pretty tight on my hips. I think it’s called a sheath dress? that I got from David’s Bridal. It’s not mermaid because it lays straight after coming out from the hips. I’m getting it bustled for the reception and I’m wearing short heels. I choreographed this wedding entrance with my dance friends and we intentionally made it so that it’s not crazy complicated and doesn’t involve me dropping low or anything like that. I will however have to bend slightly or lean over a little bit but it seems completely reasonable because we kept all that in mind.


I just went to the alterations appointment a week or so ago and felt like it was a little tighter on the hips area than I remembered. I definitely could have been just psyching myself out (I worry a lot), but now I’m terrified that if I bend or sit in the dress that I’m going to rip in the hips area?!
I would appreciate any perspective from people and hopefully some reassurance that dresses are made to move in I would think?! I wear a size 10 dress and carry most of my weight in my booty with a slim waist. I’m 5’5” and about 150 lbs and have a muscular build - I look more like I weigh 130-140. Do I have to just not really move, dance, or sit all night? I don’t want a reception dress because I love mine and only get to wear it once. I think I’m being dramatic… help lol.
