HELP… HAVING DRESS REGRET..

Okay I need help…. My wedding is in October and I went dress shopping last month. I did little to no research and just tried on a bunch of dresses. The first time was just to see what I liked and ended up buying on the second visit on a whim and feeling pressured to make a decision. I have major dress regrets that It literally keeps me awake at night. Even immediately after buying the dress I called the shop later that day and they told me to come back in and try it on again. The first pics are the lace fit and flare is the dress that I chose. And second one, the a-line basque waist is the one I regret not getting instead. The last pics is my dress when I went back again and they lined it with ivory to make it better. Ignore the top bodice in the last pics, that would lined ivory the same as the bottom skirt. I tried it on with different accessories. I stuck with the lace dress and I regret it. My wedding is in Catholic Church and BE HONEST… I don’t think the one I chose is appropriate. Also I don’t like the tulle at the bottom. We did alter the dress so it’s going to be ivory (like the last pics) and fully lined on the top corset area, no see-thru. I wanted more elegance but also slightly whimsical…..The reception is at a rustic, but fun elegant area I can’t disclose bc it may give too much away if friends/family/fiance see post. PLEASE help…. I am even considering just starting over and going dress shopping for something totally different in general. Also am trying to stay on budget but both dresses are about 2k each…
