Need urgent advice to lose weight quickly- bridesmaid dress doesn’t fit!

I would remove the zip and have a seam cut down both sides and have a mini ribbon corset added to both sides symmetrically ad opposed to a traditional back corset.

Find a good dressmaker, they will have a solution. It’s really not a good idea to be dieting when you are breastfeeding and if it doesn’t work it will be too late to do anything! Also, if you are breastfeeding, you are probably a bit bigger around the bust and dieting isn’t going to change that.

Shapewear should do wonders. But start keto and you’ll lose a few lbs. But you’ll feel rubbish the first week and it’ll affect your Bf.
shapewear should work magic and buy a cheap dress the same colour to swap into for the evening so you can breathe and eat!

Corset?

I'm in favour of asking the supplier for an extra yard (as they're American!) of the fabric, get it sent express and pre-book your alterations person.

That's if your ultra-powered shapewear doesn't work.

No bread, cake, goodies, pasta, rice, potatoes.
Plain yoghurt, protein shakes. Miso soup. Fruit.
Plenty of veg to get things moving, as such…

One week BF while eating less is fine, I think.

I've recently had a dress that should have been my size but didn't fit, it also had a zip up the side and I couldn't get it to close without brute force. I had three weeks to lose 2kg and it didn't make much difference in the end anyway, I did manage to squeeze into the dress but it was so tight around my ribs it gave me stomach pains and I had to get changed eventually. Don't waste time trying to diet. Find a seamstress asap! They can work miracles!
If your dress is like mine it was tightest around my rib cage and chest, and 2kg in weightloss didn't make any difference in that area anyway.

Good luck!

As others have said, get a dressmaker to insert a panel
You should not be dieting when breastfeeding.

Oh sorry just read your breast feeding so fasting probably isn't an option

If you fast you'll easily drop it op

I would do the Fast 800 keto and no carbs. You could easily drop 4 lbs in a week doing this. But be strict.

@AngeloMysterioso

Were they hand-made by a seamstress, OP or bought ready-made from a shop?

Can you do a week of Slimming World, I don't recommend long term, I've done SW a few times and any weight I lose on them I gain back each time I've tried I've always lost between 7lbs and 10lbs in my first week

Thats v doable. No alcohol and lots of water. 16:8 fasting and lower carbs. Lots of walking. It’s only a week so possible to stick to and nothing like a deadline.

Try the weightloss board on here too OP.
You are not going to lose 2kg of fat in a week, but I think shedding excess water and some good shapewear will sort you out no problem.

I was just going to post exactly the same as this!

Please don’t be tempted to diet or reduce your calorie intake. You need it because you’re breastfeeding. The dress can be sorted. Sort the dress, not the weight!

Where would spare matching material come from to create a corset?

A good seamstress could close that up and create a corset in the back. Or even just leave the side zip and just add the corset.

I was bridesmaid when 4m pregnant so just wore a different dress in the same colour. I'd have a back up option as will be tricky if BF to make too many changes to diet.

I had surgery last month and couldn't walk for a week. I lost 5lb in one week purely by being unable to get into the kitchen or stand at the cooker/fridge. No alcohol coz I was on blood thinners and not a single snack or nibble outside lunch or dinner times.

I bet it is bloat / water weight. Are you due on your period?
Anyway - combat this by going low carb. Eat no bread, pasta or sugary foods or alcohol for a week. The weight (retained water) will fall off you. You might lose as much as 4lb of just water in a week! You can definitley do this!

Reduce calories, but make sure you are getting enough protein so lose fat rather than muscle. If you have little ones I would assume you are fairly active lifting them, walking/running around all day anyway. You could lose 1kg in a week ok, 2kg will be muscle / water rather than fat.

And get some very good shapewear, eg bodysuit style would probably be enough to pull you in enough to zip up the dress, you can get ones that you can still wear your own bra with if you are breastfeeding.

Is there another bridesmaid whose dress is on the bigger side you could swap with? Your weight might be distributed differently than it was at 62kg. 2kg in one week is a lot to lose and if your body shape has changed slightly you might not get in it even if you do lose the weight. Adjustments or seeing if another bridesmaids dress fits you better and she gets in yours seems your best bet. A seamstress might be able to insert some fabric if there's none to let out.
I have a dress I bought before having ds. I weigh less now than I did when I bought the dress but it doesn't fit on the chest because my shape changed with all the breastfeeding.
Good luck!
