I do it all the time, and so do hundreds of other t-girls.
But I would advise having a mental ‘shopping list’ and sticking to it.
For example, item, size, color preferences and so on.
That way you don’t rush out of the shop with something unsuitable.
Just bear in mind that shop assistants like to do what they do best.
That is sell.
They know their stock and they usually just want to help you buy something you’ll be happy with.
As well as this, they want a sale/
Sometimes I carry some pictures of myself as Wanda.
It may surprise you to know, but honestly, I get nothing but good reactions.

So bearing this in mind, your best bet is to go for it.
Good luck with it all.
