Wear both

Deciding that as you've already managed to upset your wife once, potentially upsetting her again by only wearing the panties wouldn't be the best idea. You agree to wear both. You just hope that the meeting today won't take very long, and your not going to get distracted by the plug too much. You bend over at the end of the bed while Jane gets the lube and the plug. Returning to the bedroom to see you already bent over, she walks behind you and squirts some into you using the nozzle. You then feel the lubed plug being pushed against you. A few minutes after it popped into place and she gives you a quick spank on your arse and telling you to stand up.

"Good girl, now that you've got your plug in. Lets get this pretty thong on you, and then you can finish getting dressed for work."

You life your legs to step into the thong she's holding for you, and pulls it into place making sure it's holding you comfotably. Once she's finished, you had forgotten that the strap is going to keep pressure on the plug. You then feel Jane pull the front of the panties forward and tuck your dick in with a panty liner.

"There we go, now you won't be leaking precum directly into your panties, considering that the plug tends to get you excited when you wear it. I'll even give you a spare if you need one up too much. Now, I'm going to add this cami top to the deal, as it matches the thong, and I want you to be wearing matching lingerie."

She picks up a cami top from a different draw of her vanity, and then slips it on you. Rather than argue that this wasn't part of the original agreement, you just accept that this is going to be something you're now wearing. You hold your arms up as she slips it onto you, before helping you get dressed into your work shirt and trousers. You then put your socks, shoes, tie, and then suit jacket on before giving her a kiss on the cheek and walking down stairs. You have breakfast with Jane and then picking up your work bag head out the door to work.
