i wore a skirt and camisole top to have ds in.
worked a treat, i just hitched the skirt up to shove him out.
i wore a nightie with dd and it was horrible as they put me on continuous monitoring for blood in my waters and i had to walk around for hours with my nighie hitched up over the monitors and my fat naked ass on display to everyone who wandered into the room
skirt and top worked brilliantly and i had an old summer skirt lurking in the cupboard and you can get camisole tops for dirt cheap in pennies (primark)
