Hey! I first wanted to say you look gorgeous in that dress and congrats!

I think sleeves will look bombshell gorgeous here. I am definitely leaning toward a longer sleeve like this or this one. It definitely wouldn't look awkward in my opinion and as a personal lover of the Belle-esque sleeve, they also look very beautiful as seen here. Etsy has a ton of options for attachable sleeves so you can find a set that matches your personal preferences/ the dress.

I don't know if you planned on a veil but if it's still up in the air, cape sleeves like this would also look very nice with the halter top style.

In conclusion, and keeping the temp of your wedding season in mind, both styles would look amazing with a halter top. It just comes down to what makes you feel most comfortable and beautiful!

I personally don't think sleeves pair well with a halter top.
