The name of the company who provides the uniforms is Cintas, and in order to pull off the "mix and match" look the hotel was going for, Cintas sent in a team of seamstresses to do the work on-site. As you can imagine, the turnaround for these items is very fast—in some cases, says the hotel's rep, garments are available later in the day. Hyatt, it seems, doesn't mess around with hotel uniforms:
"They have dresses, skirts, pants and blouses for women and trousers, vests, shirts and jackets for men. The colors are: charcoal grey, crisp white, and black (of course, it is NY).
All hosts are fitted as soon as they are hired, then clothing is customized as needed. [What you are seeing here are] the second fittings."
As they say, if you need something done fast, ask a busy person. And these women were, without a question, busy. Hopefully they won't follow in the same footsteps as certain other Hyatt workers around the country, and leave the staff with half-sewn uniforms. That would be an entirely different look.
