My fave is a sexy matching bra and panties with hold ups. As someone else has mentioned about belts, I've had enough of the bloody things popping off, shame really, as I love the suspender belt look. I love wearing a sexy robe over the top to greet my clients, I have a gorgeous one with an open back, I fell in love with it as soon as it arrived!
I agree with many on thongs and g strings, I used to wear them religiously when I was a young'un, but cannot stand them now. I hate the lumpy look a bit of string around the hips cause (im not exactly toned lol) and my fanny lip will end up escaping.
I love the look of French knickers, but yet again, I don't have the lips for them, major camel toe! Hahahahaaaaa.
I predominantly buy work stuff from Anne summers atm, but a barely have a chest to speak of, so don't have to worry too much about the fit as no shop produces something that fits properly, so I've just got used to it and now improvise with fillets to actually fill out the bloody things! Lol. But once I have a BA I shall go crazy on a work shopping spree buying quality underwear, I can't wait!
