What's the style of the wedding?? Is it black tie, is it boho etc. This will help you a lot!! I personally loved the blue, just alter the train. The rest are all over the place. 😊
The blue is stunning on you I'd send a picture to the bride about it,she might like the train cause it'll make the whole wedding look glamorous. I loved the pink one too,that would have totally gone with my flower girl and Junior bridesmaid dresses, I got a full length burgundy/purple for my maid of honour who was the only adult bridesmaid I had. It matched the flowers on the girls dresses and brought a little autumn in (I got married the week it switched between summer and autumn)
Blue ruched dress and the sparkly ones are pretty. You still have time to alter it a bit. Shorten the train and get it taken in to fit your body better. The dior one is meh
