One of my bridesmaids had been dieting for a while and had been doing amazingly. Kinda early on I know but we were out shopping and have found lovely dresses for them, my issue is what to do about sizes. I've asked her and she wants to get one size smaller than she is now and use it as a goal rather than risk buying the right size now and then having to have it altered so much it looks odd. Its a very forgiving material but is quite slimline so I'm worried if she doesn't manage to lose the weight she won't be comfortable. There is no polite way to ask if she's confident she can do it though! I've never tried to lose weight so I have no idea how feasible going down one size in a year is, what I'm really asking is is that a reasonable goal?
