If they are like humanoid people --- head, torso, two arms, two wings, two legs --- and whether they can fly or not, they might wear a variety of clothing, depending on circumstance.
At home, being comfortable and with nowhere in particular to go, winged folk frequently opt to wear nothing at all. There's no good reason to get all dressed up when you're just going to lounge around in a hammock anyway!
For travelling by foot or working around their village, various jobs would require clothing of some kind. Woodworking, gardening, hunting, stone cutting. They'll want to wear some kind of apron to protect their bits (especially if they're guys); and also some kind of sarong or britches and perhaps sandals or boots. A belt or two with an assortment of kit bags, knives and tools would round out the ensemble.
Winged people, though often erroneously so portrayed, rarely wear any kind of upper body clothing. Shirts, vests, jackets, frock coats: all of these articles of clothing are unwearable by winged folk. No indeed! As any winged person can tell you, trying to stuff one's wings through a tiny hole in a shirt would be a losing battle!
Winged folk do, however, like to decorate themselves, and so will often wear a colourful sarong and may decorate their bodies and faces with various kinds of pigments. Some decorative upper body garments include scarves, abdominal wraps and shawls. Colourful and patterned, of course!
As for flying, for example in an airship, winged folk prefer knickers (1) with pockets, leggings, a flight cap, goggles and sometimes a bandanna worn around the face. Bugs, you know.
For those winged folk who can fly by their own power, they too prefer a kind of britches, but tighter fitting, along the lines of jodhpurs (2), which won't flap about too noisily but also offer protection and some extra stowage.
