Dress size, alterations, & weight loss

So I know this is a question to ask my bridal tailor, but while I’m waiting for my appointment.... opinions and experience welcome!


My wedding is next June (6.12.21). Because of restrictions I decided to online dress shop. Found the dress. Now contemplating the sizing.
I’m big into exercise. Before the gyms closed down I was there every day and will be once again as soon as I can. In the meantime home workouts have to do and it’s not as great. ie I gained a little weight and some waistbands got a biiiiittttt tight.
Right now I fit into a size 8 dress on my waist PERFECTLY. But the bust, hips, and length are all far too big.
Do I keep the 8 and have everything taken in and (hopefully) also have to deal with taking the waist in as well if I get back to my pre-pandemic weight/waist size?
I’m afraid of having so much taken in. I can’t imagine my waist would ever be smaller than the size 6. (And I’d also need to lose those 10 pounds I gained since March....) I think how huge the bust area is on me now is freaking me out more than it should.
So I need reassurance while I wait to go to the professional lol
