What is appropriate to wear to a wedding?

I have been invited to a wedding which takes place in about 3 weeks. I have never been to a wedding before, so I'm new at this. What should I wear? I know the commonsense things like don't dress slutty, but does anyone have specific suggestions? Do I...

have to dress up really formal? The wedding will take place outdoors in a nice park near a big lake and the weather will be warm. The invite doesn't specify how formal it is. Thanks in advance

Just wear something smart. Formal is just a specification to make sure you dont turn up in jeans and trainers but you could make this a brilliant chance to bag a new outfit, its nearly summer aswell. Just have a look on the internet, for something that you like that will suit your body shape. Dresses are always nice or even a cool high waisted skirt. Just make sure that it is respectable, and that it wont blow up to reveal your bum in the back of the brides wedding photos! Hope I helped, + have a lovely day.

I'd wear a summery effect cocktail dress in pale yellow or any pale color, cork/wood-heeled wedge and a huge hat that may protect you from the sun rays.. Ü lil accessories like drop earings and a simple ring will create that lady effect with formal touch! and the clutch bag has to match the wedge and the dress well, of course..

a nice spring dress with a cardigan always works for spring/summer weddings. you can dress it up with a nice pair of earrings and necklace. soft makeup and a nice pair of dressy sandals.

dressy outfit no jeans or anything like that and you cant ware white because the bride will ware white
