As we battle on for our worthy cause, we're approaching the brink of treacherous territory: sexy wedding guest dresses. While we're all for prim and proper style at a wedding, not all our fashion choices should come with the option of a cucumber sandwich and elderly relative as accessories. We want to put the danger back into wedding guest dresses; looks that may raise the temperature (and perhaps a couple of eyebrows) but are eternally glamorous in the vein of Marilyn Monroe, Christina Hendricks or even Jessica Rabbit. Jessica Rabbit However, anything acrylic, especially flammable or which was selected out of a bargain bin is still NOT acceptable and not because the bride says so, but because we do! Bucking the rules of tradition does not mean you have to throw all your well learnt style lessons out the window now does it!? Let us guide you past the perils and pitfalls so you can perfect your super sexy wedding guest dresses this spring.   JESSICA LITE     SEXY SECRETARY This can he a hard look to pull off without it becoming fancy dress- note: avoid accessorising with horn-rimmed specs and a typewriter... Instead, play against the stereotype with muted tones like this camel wiggle dress. The style is oh so Mad Men and oh so fabulous, especially when teamed with vertiginous heels that flaunt your pins and touches of gold for a luxe look.   SEXY HEELS The Pretty Dress Company Vintage Wiggle Pencil Dress in Camel- £95, Fiorelli Snake Skin Cuff in Brown- £50, Johnny Loves Rosie Leaf Drop Earrings in Gold- £16, Moda in Pelle Instinct Black Patent Peep Toe Court Shoe- £69.95    PARTY GIRL The sex appeal of this outfit comes from teaming a loud dress with even louder accessories so exuding a dissolute, party girl spirit (NB this is by no means a euphemism for something less savoury)  that is super sexy and fun. We LOVE the digital print on this dress as it is so unique and we think the bright pink heels really make it pop. Wear the outfit with a simple ponytail and barely there make up to keep it classy. Silence Beyond Syllables Beige Digital Print Dress- £139.50 now £104.63, Fiorelli Dip Dye Chain Earrings in Pink- £30, Moda in Pelle Kalani Shoe in Fuchsia- £99.95   ANDROGYNOUS APPEAL Now, we realise this one isn't technically a dress but therein lies the sex appeal! An androgynous take on wedding guest dressing is the casual girl's option- a look that says too cool to care which in itself is totally sexy. To add to that we think these aptly names lust shoes will work wonders by extending your legs and a flower corsage will give your outfit a girly side.
