Help with X dressing..

Hi i used to cross dress when i was younger, but stopped for a few reasons, now i want to get back into it but i have no idea on my size, as i have put on weight in the last few years and dont have a clue to what size i am now when i comes to buying lingerie etc.

I have a size 60 waist now, and a large chest (not sure of exact size as i dont have anyway of measuring to hand, But safe to say all my spread is around my stomach area.)

So any help on what size clothing to get that would fit me would be a help, and bra size i can find out as soon as i get a tape to measure.

Many thanks in advance for your help, Hope to hear from you girls soon xx
