Macros for weight loss for wedding

There is no such thing. However, you can lose body fat (also known as body recomposition). So you can eat at a maintenance level, or slightly below, and lift weights. You will slim down in inches and the scale will probably still go down slightly if you are diligent about it. The muscles will build (ever so slowly but get more defined) and you will lose fat (which results in the effect of "toning" that you are looking for). You have plenty of time. Good luck!

The rule of thumb for strength training or weight training, eat about 8 to 10 percent of your lean muscle mass in pounds and eat that many grams of protein. There are different opinions on the other two macros, but from what I understand those are only really important for competitive lifters. You can and should try to strengthen muscles while eating at a deficit to lose weight. While eating at a deficit it is unlikely that you will achieve more than modest muscle gains.

A fellow bride here, I'm getting married in March!

The only thing I can really think of (and what I do before events) is to cut down on your sodium intake the week before! That'll help with water retention and keep you from feeling bloated.
