Silver plated suits almost anyone who wants the look of real silver without the insurance anxiety, the layering habit, the one for every neckline. Think twice if you've got a nickel sensitivity or properly sweaty skin in summer, because plating is a thin skin over base metal and it will eventually ask something of you. If you want something that still looks new in a decade without any help from you, this isn't that item, and that's fine, nothing on the high street at this price is.
If you own none, start with a plain chain, nothing fiddly, no charm hanging off it, because that's the one you'll reach for on days you can't decide what else to wear and it needs to already go with everything. From there it earns its keep, if you'll forgive the phrase, by how it ages, which is honestly, slowly, and only if you help it along. The plating will dull first at the clasp and anywhere it rubs, your collarbone, a scarf, the seatbelt on a long drive, because friction is what takes a coating off faster than time does. Mine went slightly yellow at the clasp after about four months of being worn most days, not tarnished exactly, just tired looking, and a silver polishing cloth sorted it in under a minute. Keep it away from perfume and the shower, both will shorten its life more than you'd expect, and when it's not on you, it wants a small bag or pouch rather than loose in a drawer with your rings, because metal on metal is how you get the first visible scratch.
Chuck it in a bag without a pouch for a weekend away and you'll probably get away with it once, maybe twice, but do that every week and you're speeding up the bit where the plating wears through at the high points. On colour, go for a cooler, slightly matte silver rather than anything with a very high polish or an obvious yellow undertone, because the mirror shine shows every scratch and fingerprint within a week and the warmer tones tend to look more like the wear is showing even when it isn't. A simple round link or a flat snake chain photographs fine and wears fine, which isn't always the same thing. Rhodium plated pieces, where you can find them at this price, last noticeably longer than ones that are just silver plated on brass, so it's worth asking before you buy rather than after you notice.
Next time you're looking at one, turn it over and check the clasp first, because that's where the plating gives up before anywhere else does.
