Wedding outfit help, are any of these okay for 2026?

[BarbieBrightSide]

I have a couple of weddings coming up this summer and as I am particularly skint at the moment, I wondered whether I could get away with wearing one of the dresses already in my wardrobe.
I don't really know what is acceptable anymore, it's been years since I attended anything remotely formal.
I'm also considerably older than when done of these dresses got their last outings and my shape has changed.
I'm not totally against buying something new, but would love some guidance from the wise women of Style and Beauty, please.
Pictures to follow. Ignore the shoes!

The weddings are July and August

Forgot to this one!

They are fine (as long as ironed) which do you prefer? I think the brown one works well if subtle is your preferred preference, the blue one is nice, the floral is a bit too structured for me, but that’s personal preference, I’d avoid the white one and long sleeves unless it’s cool weather

I think the dark blue one is definitely the nicest.

The pink (coral?) one looks like it doesn’t quite fit you as well as the dark blue.

I think the pale blue doesn’t suit you, and is more dated. And for me, I don’t like the pattern on the brown one - that’s just personal preference though. I think it looks a bit odd in the breast area

The pale blue with flowers looks best for a wedding imo. Different shoes obvs. Some nice accessories and it will work really well. That polka dot one might work well too. Not loving the others.

All are fine for a wedding, I like dress 3 the most.

I think the dark blue one fits best and is easy to accessorize. It looks like a better fabric and I like the short sleeves. Navy is chic for summer and you cannot go wrong. It also doesn’t over emphasize your boobs! That would be a plus for me.

Sorry I think the dark blue is very frumpy. I love the brown one on you, looks lovely

The first one if I had to, assuming the way it’s sitting at the front is due to the way you’re holding the camera. They’re all a bit Wallis office vibe to me. Definitely not those shoes with any of them.

what sort of wedding is it?

Dark blue is my favourite:)

I like the third one along - cannot quite see the colour in photo - brown with swirly bits and fluttery sleeves- flattering and I think a good choice with a cracking necklace and updo and good underwear

Brown.
I think you need below the knees dress.
The last one has too much of holiday vibe.

I love the first two and the third one.

I think the brown is best with a decent bra and nice accessories. Agree with PP def not those shoes

I think the red and the dark blue would work well with good shoes and accessories OP.

OP, are you asking which ones look most in keeping with 2026 style? If that’s the case, the brown dress and the polka dot one look most “2026.” The others are all shorter and more structured than current fashions, though the dark blue one in particular is still perfectly acceptable for a wedding.

The polka dot one would be good with a black linen blazer over it to heighten the “summer monochrome” look and smarten it up for the occasion. It would look nice with a coloured (maybe yellow or red?) clutch and low-to-mid heeled black sandals.

The brown would also benefit from a blazer - maybe in natural/ecru to keep it all light and summery, with a brown clutch and brown or gold sandals and gold jewellery.

@apricotdreams it’s partially a length problem. Fit wise, the dark blue one fits best and is easy to accessorise. I prefer a waisted and flare dress below the knee but the op seems to like her knees showing. She seems to like that!

Midi would be nicer
