I have nothing against designing characters that are good-looking, or beautiful. I think everyone enjoys having a hot companion by their side. I like Liara, she's beautiful, but she also had the armor, and she was both interesting and capable. I loved the moment when we first met Ashley, a very good-looking woman, but with heavy armor, and a professional attitude.
BioWare, you don't need to sexualize characters to sell your games. I recommend that you prioritize realism, not sexualization of characters.
I don't know. When I finally got around to playing ME1, I just couldn't take Ash's armor seriously with that pink and white color scheme.
I also pretty much never used Kaiden, Ashley, or Liara in that game because, aside from just not liking any of them very much, I didn't like their armor. It all looked the same; just the same generic pieces Shep was wearing. Some were lighter, some were heavier. Some minor color or pattern variations. But on the whole, all of ME1's armor just blends together in my mind in one big pile of mediocre same-ness.
The exceptions being Ashly's Pheonix armor because of how much it stood out as being horrible, and Garrus, Tali, and Wrex, who had very distinctive looks due to their alien body shapes, but even then, I don't remember any specific suits that stood out to me.
Again, I had a certain bias having played both ME2 and ME3 before ME1, but I definitely preferred the later games in terms of character and armor design.
