Peri menopause can have a huge effect on stomach and bum. I know ...
You are lucky to have a defined waist!
The tricks I have learned:
Proper bra fitting and a set of new bras, starting with flesh-toned, then anything you like in addition.
Clothes well fitted and well defined over shoulders, bust and under bust. Not tight, but fitted.
A bit of width to your shoulders, say with angel wing sleeves, can re-emphasize your waist.
Think V-necks - not overly cleavagey, but elegant and neck-elongating. Avoid bulky rollnecks, polo necks and crew necks.
Then with skirts, as soon as the 'situation' begins - go A-line. Well cut, firm fabrics, clean line. Length will depend on your preference, height, boots/shoes, the weather ...
Avoid gathers, layers, tiers, flounces, pleats (anything bulky), and anything too tight and clingy (bias cut or jersey fabrics.)
With trousers, avoid the light bulb silhouette and stay away from tight leggings/leggings/slim fit.
Boot cut gives nice balance.
Use the same principles for dresses and tops I've outlined earlier, and go for longer length tunics that skim over the 'situation.'
(And step away from anything saggy, baggy, slouchy, oversized, camouflaging. They will create a shapeless schlumpy effect.)
Works for me, let us know!
