Wrong Underwear - I am Ungrateful

Why is your mil buying you underwear ?! That is fuckin weird. Put a stop to that shit.

Re-gift the whole lot to MIL, including the stuff she bought you.

Job done.

Good God, no to all of it! Your DH buying your bras and your MIL buying you any underwear. Just be straight and say you don’t want any more ‘gifts’. Buy your own undies, like a grown up,

Is that all you ever get? How sad. And tell your MIL to stop buying you underwear.

That's weird. Stop.

I agree with others. Tell him now not to buy you underwear. Tell him you want to wear what you find comfortable.
He ya biting it for himself. If he chooses to ignore you, then buy him underwear for his birthday and Christmas. Make sure it is scratching, flimsy, impractical stuff from a sex shop. Preferably pants with a hole on the arse or a thong. If he dared to complain tell him that he buys you impractical stuff so what’s the difference?
Also tell him to tell your mil that you do not want underwear.

But its the opposite for men - buy him a large codpiece and act disappointed that he doesnt fill it.

I suspect that he is passive aggressively negging you by buying you the smaller size he wants you to return to?

Underwear is such an odd gift. I know it's supposed by sexy, but it's such a difficult thing to buy for another person! Even if you know their size and style preferences, there are too many variables that can go wrong. He needs to be told. Would he rather the money be wasted on things you won't want to wear? Because if so, that's just stupid (and so must he be).

If he insists on buying underwear for you, you could suggest he gives you the money so you can shop for yourself, and then you come home and model them for him. (This wouldn't be for me, but if you don't mind, it might appeal to him.)

Your MIL insisting on buying underwear for you is a whole other kettle of fish!

YANBU in being annoyed but YABU in not just providing him with the right sizing? Unless he’s rejecting taking note of it?

I also don’t understand why he can’t just pop a gift receipt into the bag.

So he's buying HIMSELF presents for Christmas instead of proper presents for you, then getting pissy because you don't want them for whatever reason.

Even if they fit perfectly, they're still presents for himself, not OP, and he needs to stop being such an arse.

The underwear doesn’t fit. That’s the issue.

Nothing wrong with having day to day undies and also nicer / sexier items, but having the items fit the wearer is kind of important, or would you squeeze yourself into ill fitting underwear your husband or shudder at the thought, your MIL bought you ?

Seems like he’s buying it for himself, not you and also, that he’s found an identical, present buying method for every birthday and Christmas that needs zero effort on his part.

However, it’s no longer working, it isn’t special any more and it’s wasting your money. Just say you no longer need him to buy your underwear and suggest he buys you either nice vouchers or books you a weekend away for gifts instead.

I'm way older than you and love my day time comfy stuff, but when I go out with DH or any other fancy event I get my lovely stuff out and it still makes me feel sexy for myself and him.
Just have both, surely not a big deal?

Weird, I'm sure there's much better/nicer things she'd have preferred

Tell him now, just say you know your birthday is coming soon and that you body is changing and as a heads up you'd rather buy your own underwear now to make sure it is comfortable as some styles no longer are.

He can sort out the returns.

For MIL do that same, thank her, tell her how beautiful they are and she has great taste but you'll have to ask for the receipts. Same message, you can't wear those styles now as body changing and they are not comfortable, tell her she'll understand as she has probably been through the same.

Well, if I didn't have much money and my MIL was going to treat me to something, there are a million things I'd prefer over "nice underwear". Cashmere jumper. Fancy face cream. Nice cookware.

If she needs and wants underwear, perhaps a voucher then. But for my money, a grown woman buying another grown woman underwear is just weird and inappropriate.

For his Birthday give him the underwear that doesn’t fit you and buy yourself stuff that fits.

My sister in law once bought me a red nylon thong with fixed ribbons on it that would have shown through any clothes.

I don't wear thongs, and I can't wear nylon so have no idea what the thought process was.

I certainly don't want to think she was thinking about mine and her brother's sex life. 😂

Oh god I buy my dil underwear because it's nice to have lovely underwear and she doesn't have much money so wouldn't treat herself to it. I'm going to have to check now.
Also my ex husband would buy me underwear and I loved it - not necessarily sexy stuff just nice. The year he got the wrong size was when he was having an affair.

Your birthday his all about him - His preferred present. His mood if you don't act grateful enough. This needs to be pointed out explicitly. If he chooses to be in a mood over it that's his problem, not yours. Buy him uncomfortable underwear in the wrong size and see how he likes it.

I voted YABU because you should have set the record straight long ago.
Pathetic on your part to not speak your mind to both MIL and your thick husband.

That as well. "I thought this is what you do in your family?😇"

Sell it on ebay

Buy him the teeny tiniest underwear possible as a present?

Tell him that sizes are all over the place in marks and spencer now. Can he give you a voucher so you can get measured and try things on...even if you don't!
My dh is convinced he knows my size...he doesn't. I get the occasional fat face top from an airport.
