Wimbledon enforces a strict all-white dress code, meaning designers have less room to play with, and Svitolina said after attending Nike's Oregon headquarters a year ago, she has a greater appreciation of the work done to produce pieces the players can wear on court.
"I love my dress," she said in her post-match press conference before explaining why she was put off by criticism of it.
"I think it was not fair. It's not fair for designers, because they put so much work into our kit. They put so much effort in it, and then to say something that it was, that there was no effort, I think it was not fair for them.
"I went actually to the headquarters where I saw all the guys working behind the scenes. It's the same, like, for the tournament, you know. We go to play the tournament, and we just play and we think it's just everyday thing that happens.
"But it's so much work that put into the tournament and everything going around us, so we have to appreciate this."
Last year Aussie John Millman fell foul of the Wimbledon fashion police when officials informed him shortly before his match against Milos Raonic his undies were a bit too loud for the famous venue.
Millman sent his dad on a shopping trip to a nearby apparel store to find a more suitable undergarment and he was allowed to play on, but eventually lost to the big-serving Canadian in three sets.
Two years ago Venus Williams courted controversy by sporting a pink bra, changing midway through her match against Elise Mertens in a situation she described as "awkward". In 2015, Eugenie Bouchard was almost issued with a code violation for wearing a black sports bra, even though it was almost completely hidden.
Svitolina is seeded eighth at Wimbledon and will face Margarita Gasparyan in the second round. The 24-year-old has already bettered her effort at last year's Championships, were she was knocked out in the opening round.
"Last year it was not so good but the year before it was a great run for me," Svitolina said. "I think I can play well on grass. I just need to be really focused on what I have to do on court.
"That's very important for me just to take one match at a time, don't think too much of what's going on.
"Also be healthy. That's one of the goals, one of the priorities for me, to be fresh and to give myself a chance to actually play well, because I think, you know, I can play really good. It's just a matter of getting more time on the court and just be focused on what I have to do."
