Long sleeve dresses in summer

As a person who absolutely MELTS in the heat, I wouldn't be down for this lol.

I'd run it by your bridesmaids. They're the ones that will have to wear it. Even sheer material can be super hot (if its a synthetic, its won't breathe very well).

No not at all i have my girls in long sheer dresses as well!

As long as it isn't going to leave sweat marks under their arms from it and you are in air conditioning for your reception I would say it's up to you and your girls. If more than one of them object or raise concern then I would say to try and avoid it.

I agree with the others, I think your bridesmaids will be very uncomfortable in long sleeves.
I got married early September and my dress had a sheer, illusion neckline and back. I found that part of the dress very hot. Also, illusion fabric will stick to sweat and, frankly, it doesn't look good when it does this.

I don’t think long sleeves are a good idea if you’re outside at all. If you’re in air conditioned comfort all day, then you’d probably be fine.
It comes down to absorbency and how breathable the fabric is. Any fabric that isn’t natural (cotton, linen, nylon) won’t breathe and won’t absorb much, leading to sweat central for your bridesmaids.
Sheer material has the same problems as thicker poly material (especially since it’s guaranteed man made) so even though it looks light, your bridesmaids would be hot and racing for the deodorant all day. You probably would be best to keep it sleeveless as best you can and keep them comfortable.

I'm also having a July wedding. I wouldn't want my bridesmaids in long sleeves. You could luck out & have a cool day, but more than likely it'll be warm & they might get uncomfortable quick. But if you're having an indoor ceremony/reception then that would be different.

I'm having a July wedding and it'll be outdoors, and I wouldn't make my wedding party wear long sleeves no matter the material. I feel bad enough that FH wants to wear a 3-piece suit! But it was his choice, so I'm not going to bug him about it. I also have a problem with heat and get affected by it easily if I don't take the proper precautions. So I'd be talking to your bridesmaids about it at the very least

If you're outside it would probably be too hot. Plus with sheer sleeves you might still need to put sunscreen on which means they might need to take the dress off to reapply.
If you're indoors it might be more comfortable.

I wouldn’t do long sleeves in july - it’ll be way too hot. My sister is in a strapless but long dress and it’s really elegant (I think anyway! But I’m probably a little biased lol)

Yes. It will most likely be hot. It’s not like crazy but yes even sheer sleeves can be hot. Fabric is gonna be the main factor. Mesh fabrics typically don’t breath. Chiffon is great but if the lining of the dress is not a cool fabric you can get sticky and hot in other places lol. Depending on the quality of tulle or netting sweat doesn’t evaporate through it and it can be hot. The style of sleeves or sleeveless itself doesn’t matter as much as the fabric and lining. Think of normal clothes I’d rather wear a sheer long sleeves blouse in the summer than a wool tube top! Kind of a dramatic example but I think you get the drift LOL

Are you inside for air conditioning most of the time or is it mostly outside? I personally find bridesmaid dresses hot enough never mond adding sleeves in July... have you felt the material? Does it feel really light?
