Feeding at home is a clothing problem you can solve badly and get away with. Feeding somewhere else is the one that decides what you actually wear, because it has to work while you're sitting awkwardly, holding someone, possibly being talked to, with one hand and no mirror.
Most of the advice about this is about confidence, which is fair but not much practical use at the time. This is about the clothes, which you can decide in advance and then stop thinking about.
The principle: cover the middle, not the front
Here's the thing that surprises people. When they picture feeding in public, they picture the front being exposed. In practice, the front is almost entirely blocked by a baby. What actually ends up on display — and what almost everyone wants covered — is the middle: the strip of stomach and side that appears when a top is lifted.
Once you've noticed that, the whole clothing question changes. You don't need a cover, a scarf, or anything draped over anybody. You need a garment where the bottom layer stays down.
That is precisely what a double-layer top does, and precisely what a single jumper does not.
The outfit that needs no planning
A stretchy vest underneath, always. This is the layer that stays put. It stretches aside for access and covers your middle throughout. A vest with a wide, flat hem band is better than a thin one, because it grips rather than rolling up.
An outer layer that lifts or opens. Loose knit, crossover top, wrap, button-down shirt. Looser is better than fitted, because a lifted fitted top has to be held up.
A long cardigan over the top. It closes off the side you're not facing away from, which is the one that bothers people. It does more than any purpose-made cover and doesn't announce itself.
That's it. Three layers, all of them ordinary clothes, no hardware, works anywhere.
Things that quietly make it harder
Dresses without a front opening. A dress that doesn't open at the front has to come up from the bottom, which is a very different proposition on a train.
Jumpsuits and playsuits. Complete undressing. Lovely garments, wrong season of life.
Fitted tops in fine jersey. They have to be held, they ride up, and they stay creased afterwards.
Anything you have to unfasten behind you. Back zips and back buttons are the definition of a two-handed job.
Crisp fabrics that crease. Linen and fine cotton shirting look wonderful and then look slept-in after twenty minutes of being bunched up.
Fabric and colour, practically
Mid-weight knits recover their shape after being lifted; fine ones stay stretched and rumpled. That single difference decides whether you look put-together for the rest of the afternoon.
On colour: mid-tones and prints are simply more forgiving than flat black or white, both of which show every mark. It isn't a compromise — a good print is a practical garment.
And whatever you wear should be washable at forty without ceremony. This is not the phase for anything that needs handling.
Coats and the cold
Winter is the bit people forget. A big coat with a zip that opens upwards from the bottom is genuinely useful — you can open it from below without taking it off. A coat that only opens from the top means removing it entirely in a cold café.
A long, open cardigan under the coat does more good than a thicker coat, because it's the layer you actually keep on.
And the bit that isn't about clothes
Dressing for this well doesn't make anyone confident. What it does is remove the small, specific worries — will this ride up, can I do this one-handed, is my back exposed — so that the only thing left is the part that's genuinely about you and how you feel, which no garment was ever going to fix.
Sorting the clothes out in advance means you get to have that feeling, or not, without also fighting a jumper.
