Wibu to not have a spray tan?

[GetTheeToANunnery]

I'm a bridesmaid in my sisters wedding soon. I've already had comments that I should try lose a bit of weight before the event (always been a size 10 but recently gone up to 12-14, I think she actually thinks she's being helpful by saying this), I need to make sure my hair looks nice with no roots (I dye my blonde hair brown but sometimes leave it a bit longer between dyes than she would like ) and now I have to have a spray tan before the event.
We're both naturally pale but she prefers the orange look, whereas I prefer my natural colouring.
I don't want to end up orange, I don't want a list of things I have to change about myself. Is this normal for a bride to have these demands?
I thought making sure my hair looked good was a no brainier, I'm not stupid enough to turn up with it in a mess.

Since you dye your hair anyway, I would assure her it will be looking nice for her wedding day.

I think her asking you to get a fake tan is disgraceful. I think our society has become sick wanting people to dye their skin. I would tell her to get a blow up doll as a bridesmaid then she can make her up, dress her up, paint her and blow her up to get the required size and colour.

I think she is being a cheeky mare. That said, the only time I have had a fake tan was when I was a BM and we were wearing strapless dresses - am vv pale. Salon recommended a St Tropez non spray tan, and it was very subtle and looked great in the photos
