How long do dress alterations take?

I would go in about 2 months before the wedding. I took my dress in about the last week of August .They hemmed my dress, added a 9 point bustle, added a belt, and added a sweetheart neckline and I am picking it up wednesday. My alterations are from Davids Bridal. My alterations took about 3-4 weeks. But you have a lot more to get done then I did.

Definitely start at least 2 months before the wedding - and good seamstresses get booked up, so get on their schedule now!

They can start with things like hemming and sleeves now. If you tell them you're planning to lose weight, they can wait on taking it in until a later fitting.

I did mine at David's bridal and it's taking 3 weeks for them to be done.

I had my dress hemmed (it was really complicated because it swoops a lot), cups put in and added a bustle and it only took my seamstress a week.

I was told 6-8 weeks

It all depends on how much work needs to be done & how busy your seamstress will be. I need a 1-point bustle and cups put in (nothing else... no hem, no taking in) and I needed the dress to my seamstress 8 weeks ahead of time. I'd suggest you reach out now so you are on time for alterations.
