[Nospringflower]

Trying to buy these from ASOS with 20% off so need to do it before 5pm!
Wanting something for a friends sons wedding reception - evening do - and hoping it will also be wearable for other summer things.
Dress 1 here
Dress 2 dress 2
or this www.asos.com/pgeproduct.aspx?iid=2114821. I am size 8/10 and 5 foot 4, small build.
Like this Reiss one too.
Drop waists suited me when I used to wear them but not sure how fashionable they are / will be. Should I just wait and take me time??
Thanks a lot.

Didn't see this in time. Which one did you get in the end?

I just ordered them all! Decided with free delivery it didnt really matter if I didnt like any of them!

That makes sense! Fwiw, I like all of them but especially dress1. But, far better to try on and home and see what suits.
