So I took my dress and went to an alterations place to get a consultation and got a big shocking price that I can't get over. I am going to get some second opinions but I was not ready to pay $300 in alterations just for what the bride shop said were small alterations. The dress almost fits me perfectly but I need a bustle and small off shoulder sleeves added. My dress is an Allure all lace dress and doesn't have any beading work.
I was so upset though and now I'm worried I'm being unrealistic and will end up paying that much anywhere. How much is realistic or unrealistic?
The dress and example of sleeves are attached.
