Should I give my honest to God opinion or just keep quiet?

Honestly, I prefer her choice. Wax seal is lively but overdone. A friend had a wedding recently with all the bright colours of the alleged bad taste invite you posted and everyone commented.
Let her be slapdash and chilled. It's her wedding, her personality and a thousand times better than a bridezilla or a nervous breakdown.

This!

Have an opinion about whether her fiance is abusive (if that was an issue) but these things should reflect her taste, not yours.

Sometimes appealing to the norm is more important e.g. job interviews. Otherwise leave well alone.

When she asked that, was there a choice of designs? Fine to say which of the choice you like best. Not fine to expect her to go with your opinion or to suggest other new things unless she asks you for other ideas. It sounds like you answered but want to go back to discussing it because you didn't like her response to your answer.

It's an invitation, it's not that important.

Stop interfering! Pathetic first world problem

If you're like this about a perfectly fine wedding invite that most people will just take the information from and then bin there is no way you'd be anywhere near the rest of my wedding planning. You'd get your 'shit' invite and then that would be it see you on the wedding day

One person's slapdash is another person's laidback. One person's "attention to detail" is another person's controlling.

You have a problem, and it isn't your poor sister's wedding invites.

Anyone can use a glue gun to stick some lavender to a Blue Mountain Arts card.
I thought those wax seals were condoms.

If you're on here showing us how poor her taste is and how good yours is, why did you show us a style that you subsequently said you didn't really like? You sounded pretty invested we you said you'd help with the wax seals and ribbon tying.

I like the flowery border.

Weddings are so stressful, don’t over complicate your sister’s planning by bringing in totally different aesthetics and ideas.

And relax a bit about your taste - perhaps consider that your friends and acquaintances might have quite a narrow idea of ‘taste’ as well. It’s okay for other people to think differently. There is rarely a right and wrong to these things. Have fun looking at dresses.

You just like different things, she’s not making a mistake. You really need to let it go and realise that you don’t have ‘good’ taste, you have different taste

My wedding invites coat 89p in the Card Factory sale, god knows what you think about me 🤣

There's times where you can give your honest opinion, and times when you really need to smile and nod because your opinion isn't the be all and end all. I know someone who has to give his opinion on EVERYTHING, I try not to spend too much time around him because it annoys the hell out of me...

No one gives a shit about ribbons and wax seals 🙄. (Well, some people clearly do!!) of you’re getting this wound up over invitations, I feel sorry for your sister for the rest of the planning.

This.

Good grief - Noone fcking cares about an invite.

I've been to loads of weddings - if you asked me to describe what all their invites looked like, I couldnt. Thats because I cant remember. Thats because it's not important and that information was considered so damn irrelevant by my long term memory storage that it binned it once the wedding was over.

Noone gives a fck about a stupid invite.

You see I think that looks naff, but if it were your wedding preps I’d respect your taste and say nice things.

Guilty conscience?
I wasn’t talking about you.

I was talking about having a bullying sister in general.
wow

Respectfully it sounds like you have different tastes, and she likes her invites. She’s already got annoyed with your suggestion. It’s her wedding. It’s not your place to be critical here and dampen her joy.

None of the guests care what the invites look like. They just want to celebrate the happy couple.

I like the floral border! To me it says “fun wedding” rather than “tedious stuffy wedding”.

You’re making its sound like it’s a right or wrong ‘answer’. It’s not.

You have repeatedly defended ‘why’ on this thread and never once expressed, maybe other people like different things to me.

I’ve received some elaborate wedding invites that you would deem appropriate. I look at them for seconds and that’s it. Nothing to do with taste. I don’t display them. People don’t all sit there fawning over a wedding invitation even if it’s in the same style as they would choose. It’s not at all what people will remember. You need to chill.

This. You are being controlling and deliberately shading her - I suspect you have always done so maybe to make yourself feel better about yourself. So unpleasant.

It does sound like this to me. OP I agree you sound controlling. And it sounds like your' brutally honest' despite your claim it goes both ways just doesn't. You tell her what to wear or not. You criticise her choices. You sound quite overbearing- even just on this thread you sound forceful and incapable of considering another view may have merit. It might be worth your while giving some serious self reflection.

I have no opinion on the sister thing except for OP to stay out of it - apart from anything else, the last thing you really want is to get assigned jobs by a stressed bride when you have differing opinions on what things should look like. Better to just keep your head down IMO

BUT, that second wax seal example makes no sense and it's bugging me. The name is on a bit of grease-proof/tracing paper, with the wax seal in the middle, on top of the paper, it can't be holding the greaseproof to the menu below - well, unless they punched a hole in the middle so the wax could seep through? But that would be madness. And that's assuming it'll stick to the tracing paper at all.

The ribbons/wax seal/bits of plastic scream Amazon to me…

Your sister is right. Literally no one (except you) cares. Normal people are just interested in the content of the invitation (when is the ceremony, what are the meal choices, is it no children, do I have a plus one?) and anyone judging something so utterly trivial seriously needs to be uninvited.
Get a grip of yourself and stop making this about you. When you get married/remarried you can create a bouquet of wax deals or wax seal your veil to your head for all anyone even cares, because it’s YOUR day. This isn’t.

My 14 year old DD and her friends are NOT into traditional ‘shopping’ - they are into charity shops, Vinted, will not use Amazon or Temu etc
I really think that’s the direction ‘fashion’ and ‘good taste’ should be moving.

Not sure I’d use “ribbon tying and wax seal applying” and “good taste” so close together!🤣
