Help! Bridesmaid dress doesn't fit. 2 weeks to go..

Do low carb for 2 weeks.

A tailor at the cleaners can add a panel to it. Maybe the store where you bought it has some of the same fabric. Though you did say you didn't want to go that route. Like 35 years ago when getting fitted for a bridesmaid dress, I told the seamstress to make it like 2 or 3 sizes smaller. She did. I didn't lose the weight. She had to add a panel to it. You need to feel comfortable in it to be able to dance, eat and have fun for those hours. Can you get a camisole in the same color and wear it underneath or where one of those shrugs?

Have you tried flexible eating? I lost 5 lbs in a week just by having my macros in the correct balance. It's great because you don't have to give up carbs! :-)

Try the GM diet, it will definitely help to lose weight fast. Basically this is a low carb and calorie deficit diet which truly helped me. Google for more info on that.
I tried so hard exercising and eating under my calorie goal, still struggled to lose weight. GM diet kick started my initial weight loss.

With 2 weeks still to go, why isn't getting it taken out an option?

My suggestion is to start doing OMAD immediately, go low carb or keto while doing OMAD, and drink only water, mineral water, unsweetened tea, or black coffee throughout the day. Nothing with artificial sweeteners. Don't restrict calories during your one meal. I believe if you do this you will fit comfortably into your dress. Good luck.

I've been doing a -1000 calorie deficit since March, but not following any particular diet other than exercising daily and trying to eat good fats (avocado, black beans, walnuts, etc) and good carbs (fiberous fruits, whole grains) and plenty of lean protein. And that's a "2lb per week" diet. If you're not already dieting and exercising, it's reasonable that you could lose 4 lbs from a healthy, calorie-deficit with exercise. And like others said...if you just started, you may actually lose more like 5 or 6 pounds from initial water-loss.

I don't see why you'd need a crash/temporary diet at all because for me...every 5 lbs is about one clothing size in odds (juniors) or evens (ie: if you're a Size 10 ...you'd be more like a Size 8 or Size 11 more like Size 9). And I very much agree on the shapewear. Get a strong latex waist trainer and just throw it on for the event and that will shave a few inches off, too.

I say do a normal, healthy diet, exercise daily (which makes the -1000 deficit easy to maintain, and add the shapewear and you'll probably fit the dress unless it's wayyyy too small (Like a Size 6 and you're currently a 10). A crash diet will only make you gain back all of it and likely screw up your body for awhile afterward. It's not worth it.

Shapewear and corsets are a fabulous fast fix with no long term damage. A long latex trainer will cover the most torso area to ensure abdomen and upper back are as cinched as possible. Try "Ann Chery - Style 2021" available lots of places (I have this one):

For a similar one that has a "vest" for the upper back/back Fat, try this one:

I have a steel-boned real corset, as well but I don't recommend them under fitted clothes and you have to break them in slowly for weeks. Plus they're expensive if they're quality.
