This is a girl's dress after all. Putting it on would be plain stupid. Giving it to someone more suited to the task, however...
You dial your girlfriend.
—Hi, honey, you busy? Can you talk?
—Yeah, sure! What's up?
—Wanna hang out at my place? I have a surprise for you!
—Whoa~ I'll be there in a couple of hours
—See you soon!
Great! Now just to wait... Where's that TV remote?
~~~
An hour and a half earlier you hear someone knocking on the door. She's early!
'Heeey! I managed to finish my stuff early so here I am!' — your girlfriend says. She looks a bit winded; working on weekends gotta suck, even if it's part-time.
You embrace her and give her a kiss. You girlfriend is a petite girl, not taller than 5' 4 (164 cm), so she has to stand on her toes to return the kiss.
'I've been waiting patiently'
'So what's the surprise? Show me, show me!' — she begs impatiently.
You show her the table with all the latex clothing glimmering in the sun.
'—Whoa. Did you buy this for me?'
'—Not exactly. I found this stuff in a box on my doorstep this morning'
'—Are you sure it's safe?'
'—It's just some rubber, I doubt that it's harmful or anything. Probably a mail mistake' — you say, hiding the fact that the box had no labels or inscriptions on it whatsoever. You want to see your girlfriend in this skintight outfit way too much to miss such an opportunity.
She picks the dress up by puffy sleeves, broodingly looking at the frilly hem. She grabs the bow and squeezes it with her well-manicured fingers. 'Nah, it's a unique chance, gotta use it' — she finally says.
She takes off her shoes, blouse, her skirt, pantyhose, bra and panties. You can't help but admire her slender figure with round ass and ample breasts. 'Don't stare at me like that' — your girlfriend pouts, sliding ruffled latex panties up her legs. The bra turns out to be a little smaller than her breast size, squishing them a little, but you like it even more as it brings out her nipples.
Putting on the dress requires some help from you: she seems to have trouble finding the hand holes. You easily guide her and then pull the dress down, freeing her head and her curly long chestnut hair. You run you hands down her waist, flattening any latex creases as your girl zips up the dress. You help her with the apron as well, buttoning it up so that rubber straps don't cover the giant bow just above that plump ass.
Putting on stockings and gloves takes some time, but you two manage to do it, albeit not without an occasional pinch or two.
'Owww! Dont' pinch me, it hurts!' — your girlfriend makes a sullen face
'Sorry, honey, I'm just trying to help you with the creases'
Finally, she puts on the petticoat, making the skirt look bigger and adding even more fluffy cuteness to the outfit. You two move over to the mirror.
'Waaaah~ I look so cute' — your lover says with glee.
She looks like true a sissy fetish servant in this purple dress adorned with countless black frills and bows. You hug your girlfriend from behind and complete the outfit, putting the headpiece onto her hair. She looks positively amazed with how pretty the dress is. You give her breasts a light squeeze.
'Ahhh~' — she moans, making a helpless, cute face.
'Are you ready to serve your master?' — you whisper in her ear as you get seriously turned on by this latex beauty
'Yes~ I am'
