How to decide on bridesmaids

I don’t think 4 and 7 would look strange !

Uneven numbers are fine. Pick your nearest and dearest most supportive people. Do not pick anyone out of obligation. This is a role that is too important to pick random in laws, childhood friends and others you are not currently bestest friends ever with. Also wait until 6 months out to decide because there are countless posts where people picked folks up to 2 years out and have unnecessary drama as a result.

4 and 7 could work out! You could have the MOH and best man both walk in together, and then have each of the groomsmen paired with two bridesmaids. The sides don't have to be even. I would suggest only picking those who you truly want by your side and can't imagine your day without. Don't pick anyone out of obligation or just because they asked you to stand up in their wedding or just to even out the sides. If that still means you want to include all 7, go for it! Otherwise, you'll find a way to make it work with however many people you choose.

4 and 7 would not look strange! You should select only those who are nearest and dearest to you, and very often that is a different number of people for each member of a couple. One other idea you could consider is having your FH's sister be a groomswoman instead of a bridesmaid - she would stand on his side but of course could still get ready with the bridal party, etc.

Mismatched bride and groom count never bothered me. I have a small wedding party 3 women, 3 men. BM and MOH included in the count. I think it’s becoming more accepted to have an uneven number of bridesmaids and groomsmen. You can always switch up the procession so that two groomsmen walk out with one bridesmaid if there’s more men than women or two bridesmaid with one groomsmen. Whatever feels right you should go with.

We decided on having none. It was too much stress keeping up with everyone.

The uneveness won't look strange if you work on ways to switch everything out. Such as having the bridesmaids and groomsmen walk out seperately.
