Believe me, she once said that would be a divorce if I ever did it, so I know she is serious, though I also know she will come round in time.
On the other hand, we are more or less the same size in clothes, and far from us having an ethical issue with me ‘borrowing’ her clothes, she has outright said that if there’s any I want to use, go right ahead.
She has actively encouraged my dressing at home at least when she’s not around, and is happy for me to be dressed when she is so long as it isn’t in ‘girl’ fashion.
That is, catsuits and trouser suits and lingerie under clothes are fine, but she hasn’t yet seen me in more feminine attire.
