Shoes or boots?

How about your bike boots

I remember shooting a wedding with a tea length dress and they had lace ankle boots which could possibly work as a halfway option. As you already have your dress then perhaps you can order options for home delivery and see what works.

I have a tea length dress also and need shoes that are stable and comfy as I live in flats so have gone for something like this:

Like Bill said, maybe go for bike boots if that's your thing or some converse, that you can bling up to add some quirkiness. Have a look on Esty, there are loads of decals you can buy to add to your shoes, and they also sell some quirky shoes that may work

I have a tea length dress and for the evening reception, I am changing into wedding Converse with white ribbon laces and the words "I do" in blue (our accent colour) on the heel. There is a website:

Good luck!

One of my cousins had her bridesmaids in tealength dresses, and they wore sandals (in December - brrrrr!) for the ceremony, and then changed into boots for the reception.

I think boots will look fine, but if you can't find a pair you like, you could wear furry boots to travel to & from the wedding and then just wear flipflops for the ceremony and photos!
