Sexyyy Picture Help??

Okay, so I'm a big girl. 5 feet and 200 lbs. So pretty overweight. I am also 20 weeks pregnant, so not looking the sexiest.

So... the thing is, i want to send my spouse a "sexy" picture to tease him... but i dont know how to do it and make it actually look good/sexy being overweight. Ive never done it since ive gained so much weight, so Im nervous or it not looking good etc.

Any advice??
