help needed please with wedding outfit

[mum12345678910]

hello im new here just wondered if anyone could give me any advice with outfit for wedding on saturday.
basically iv only been to 1wedding years ago and was a bridesmaid so am really clueless.
Wedding is in a church with meal after and then evening reception so needs to be suitable for all day although in country it will be indoors, needs to be a dress but not sleeveless/strappy as i hate my arms never wear dresses but recently bought and wore one for my holiday really liked it but not sure if it is suitable for a wedding any advice would be gratefully received
this is dress i have www.polyvore.com/select_butterfly_tea_dress/thing?id=50215902

exactly same as the picture but has some pinky colour on and butterflys are pinky and grreeny colours it comes to just above my knee i was thinking of wearing this with maybe beige/neutrel wedges do you think this is nice enough for a wedding?
if not does anyone have any ideas of suitable dresses i have spent ages looking round shops but ended up with nothing.
sorry for the really long post and thank you in advance for any help

yes its fine, inless you need a hat but not if your wearing one of those things you stick in your hair debinhams have some nice butterfly ones

thank you no i dont do hats and hadnt even thought about my hair!

think just as iv never been to a wedding i dont have a clue so wasnt sure if was ok for wedding am about to have another browse of the shops to see if i can find anything, thanks again for your help

i think their called fasinators but im not sure

The dress looks lovely, I think it would be fine for a wedding. I've been to quite a few weddings and I would say the majority of guests weren't wearing a hat/fascinator so you can definitely get away without one if you don't like wearing them.

cool i got the name allmost right, i agree you dont have to have one people tend not to require it these days but its nice if you enjoy wearing that sort of thing and want to
