pyjama tops with large cup support

[coastalimpact]

I'm a 30J bra size and in my 50s so getting a bit saggy. Normal pjs are now (a) unflattering and (b) a bit uncomfortable.

I've tried the Bravissimo pj tops which are ok but the built in bra is too much like a normal bra - quite stuctured with synthetic fabric which is sweaty for night time. I can't find anything else similar. What I'm looking for is either a pj top with built in support that isn't industrial-grade daytime level. Or maybe a large cup crop top or light night bra that I could wear under a normal vest. Has anyone found anything like this?

I'm also wondering if people wear their normal bra size in nightwear e.g. would I be better going up a band size or two for more comfort and less tightness?

Have you seen the M&S sleep bras, they do a fuller bust one? They do support PJ vests as well but only in regular size I think.

Thanks AliBingo, I'll have a look. I can never get bras to fit me at M&S but maybe the sleepwear is better.

Does it need to be built in? I find wearing a stretchy crop top like bra under lounge wear gives me much more flexibility, and I imagine might give you a bigger range to choose from.

Asda do a great “sports” crop top that suits me at a 36L for sleeping. They come in packs of two and cost about a tenner.

I sleep in these from Tu. They aren't very strong support but they are light, pretty and very comfortable. They also do some soft crop tops/bralettes that are excellent.

I also recommend the M&S sleep bra (the larger cup option). Then you can wear any pajamas you like.

THanks for all the replies. I've just ordered an M&S sleep bra to try and will look at the other suggestions.
