Help me to avoid nakedness for anniversary date - what's good for huge norks and postnatal tummy?

[ThisBabyIsAnOctopus]

By some miracle my parents have offered to babysit DS for DH and I to enjoy a date for our wedding anniversary. I've booked afternoon tea in super posh (but relaxed) hotel - but I'VE NOTHING TO WEAR!
I'm still bf DD (7mo) so am humungous of nork (38FF) and have a big post-natal c-section tummy (size 16-18), and a hourglass figure underneath the flab.
I really don't know where to start - my figure has changed so much since having babies and I've been living in leggings and baggy t-shirts since having DD.
I have very low requirements - 1: not be naked, 2: wear something that fits round boobs and flatters tummy as much as possible, 3: possibly allow me to bf DD (but not essential).
Any pointers?

How about a fitted wrap dress

Good suggestion but I struggle to find one that doesn't gape at my boobs and fits properly round my tummy

Have a look at asos they have a fee for breast feeding to.

How about something like this

Loads of styles and colours on the website.
My youngest is 24 so I can’t vouch for quality

Also have a look at Seraphine - they do wrap dresses that fit your figure type, or maybe try Pepperberry (Bravissimo) for a dress.

This is really flattering on and good for breastfeeding. I have a similar shape to you and bought it when they had a 20% off code!
