Surfing on the web page of one of my favorite radio stations, I ran across this image of altar servers in white — not albs, but something like jackets.
Never saw anything like this. In my first parish as a music director, teens only were altar servers, and they wore “nice” clothes–no albs.
I’ve been in parishes with a variety of alb styles: zippers and velcro, hoods and pseudo-hoods, cinctures or not, black and white.
With these young ladies wearing skirts, I think the white tops look stylish. But I put the question: are they too much a departure from traditional albs? Do they look too much like chef uniforms? Or doesn’t it matter?

Wait til one of the young ladies shows up in slacks, jeans or capri pants (do they still wear those awful things?). Then we’ll see how well received these “minis” are received.
I have a chef uniform that looks just like that…
I’m curious what gave rise to them. Was there a problem with standard albs?
This is an Alaskan adaptation.
Once when I was in Alaska, I was privileged to serve as a deacon at the cathedral in downtown Anchorage. While I wore a dalmatic, the other deacon wore a similar garment at the altar; it looked very much like a large parka. I asked about this afterwards, as the cathedral obviously had dalmatics, since they gave me one to wear. I was told that this was a common liturgical attire for deacons (and apparently other liturgical ministers from your photograph) in the remote areas of the archdiocese, and this custom was respected for those deacons when they ministered in the cathedral church. I don’t know more than that, but it would be interesting if you could dig up some information about this fascinating local adaptation.
Anchorage (as well as Juneau and Fairbanks) is technically a mission diocese, so there is apparently some greater leeway in adaptation than in non-missionary dioceses as they are subject to a different Vatican dicastery than other U.S. dioceses.
