It's all down to what femme size you need to fit. I still have a very male figure, with a bottom half that fits size 14, but a top half that needs size 18 across the shoulders, but ends up somewhat loose around the waist.
I can buy things like skirts and blouses in ordinary stores, and that gives me a certain buzz, for sure. Shoes have to be remotely selected on the net.
I've had a dress tailor made by Kentuckywoman UK which catered for my figure, but to buy one in the high street I would have to consider a very low backed halterneck design, which wouldn't need wriggling into. As I never go out 'en femme' I'm obviously buying things for presents for wife/ daughters...so the fitting rooms remain out of bounds, of course. Also I make sure I keep the receipt and discuss exchange terms 'if it doesn't fit' with the salesperson.
I am currently expecting delivery of a blazer & skirt suit made to my measurements by Crossdressing NL. How that fits will be interesting as it's my first order from them. I'll keep you posted....
