The cost of wedding lingerie is certainly not as small as the garments themselves. What you'll need depends entirely on your dress (if it's lace, backless, or strapless, you may not need or be able to wear a bra), but you'll probably want something a bit more special than your usual. Make sure you have a dressing gown you love, too, unless you want your wedding photographs to feature your tatty old number with the Care Bears on it. Set aside £100, or a lot more if you think you want to go super luxe.
