Wedding outfit help.

[Mendeleyev]

I'm going to a wedding at the end of June. It's a two day affair so I need 2 outfits. I've got one already - a boden dress reduced from £150 to £37 in a beautiful turquoise. I need another! I bought another dress which sadly doesn't fit well so it's going back.
TBH I'm reluctant to buy another dress unless its something I can also wear every day too, but I worry about being smart enough. Has anyone got any ideas of other outfits I can wear? I did think about a dress like this but is it nice enough? What would i wear it with?
I don't want to spend too much as I'm a bit tight. I'd also like to be able to wear the outfit afterwards for work (I'm a teacher and can get away with wearing pretty much anything).
I'm 5'6" and a size 8 with boobs. Autumn type colours suit me. No black! TIA

The white stuff dress isn't v smart...

How about m.johnlewis.com/mt/www.johnlewis.com/whistles-jessica-dress-red/p463062

It's a lot of money but worth it if you'll get more wear out of it...

It is lovely but I think red is a no-no. It's an Indian wedding so I think the bride will be wearing red.

This is lovely and could be dressed up with heels and a clutch or down with ankle boots and leather jacket.

What about this?

The mango one is lovely but short Orchid. I wouldn't have the confidence to carry it off. Shame as its a really good price. The Mary Portas one is lovely. Do you know if all HoF shops carry her stuff, Tethers ? Is my only option a dress then?

How about hiring or borrowing a lenga?

It might be worth trying, the models are usually 5'10 so it may be a fair few inches longer than it appears in the picture.

If you're handy with a needle you could add a late hem on the bottom to lengthen it

This is nice too:
