I realize I do alot of posts on MMPR: The Movie and here is another. Anyway, I never saw anything like this comparing the costumes of Power Rangers from the show and the movie. For the Rangers, Rita and Goldar, I compare the original Zyuranger.
Zordon
A big upgrade, we can see his lips move in sync with what he is saying! Obviously for the show, they blurred his mouth so they could make him say anything and match with how Rita's mouth didn't match what she said. In the movie, it was a new actor and instead of being aqua, he was white. And the effect was pretty good.
Alpha 5
Same voice actor, different suit actress. He was slightly taller, way shiner bulkier helmet with a bubble over his eye visor. His shoulder pads were skinnier and body was boxier with darker lightning bolt on chest. His arms were a darker grittier blue. His glove fingers were more segmented.
Lord Zedd
The silver things around him were boxier, while the original was rounder. Correct me if I wrong but the tube veins are missing. His silver is shiner and his brain is more red than pink. His 'smile' is also more crooked.
Rita Repulsa
Her movie outfit was more similar to the show version because the brown is the same shade as the show one and the neck dress is simpler than the Zyuranger version. The blue things were thicker and pointier in the original. Also the breast plate... it was more put together and black, in the movie you can see the brown. Also, I can't find a picture of this but I swear seeing the TV Guide picture of movie Rita, that she had car seat straps on her breast plate. But since she barely had any screen time, I don't blame them for not working that hard on her outfit.
Goldar
I don't know how to describe the change, they look similar but different. His chest is rounder and simpler, the original version was more detailed. His original shoulder pads had 3 chambers, int he movie it was one part. His face was closer to the American version. The original looked like a dog but the movie version looked like a fatter piece of rock. His horns were rounded and more arc. His wings were triangular.
Red Ranger
I am probably going to say more here, it is the same for Blue and Black, because it is a uniform. There was one diamond in the front versus have a diamond and two triangles since they were to look like teeth. The back had two diamonds, which I didn't like because many people mistake them for diamonds but they were to be teeth. The gloves and boots have ranger-colored arcs. The black buckles of the Power Morphers are ranger-colored in the movie. Their hostlers were ranger colored and black trim versus the original white with red trim. Obviously they had Ranger coins on their chests, here changing from Tyrannosaurus to Ape. The Tyrannosaurus symbol was slightly different from the Zyuranger version. As for the helmet, the mouth piece was boxier, the mouth bottom was more arced and the design was similar but widen.
Pink Ranger
Instead of skirts, Pink just had boobs in the armor. The back did look like she had a skirt but it was a flap. I didn't personally like Pink's helmet, I didn't like the arced wing on the face and the protruding Pterdatyl head. The original had a pink stripe in the back, here it was more white. This helmet design, along with Blue was my least favorite. Her chest had one diamond in the front versus have a diamond and two triangle. The back had two diamonds, the gloves and boots have ranger-colored arcs. The black buckles of the
Power Morphers are ranger-colored. Their hostlers were ranger colored
and black trim versus the original white with red trim. Her chest coin went from Pterodactyl to Crane.
Blue Ranger
This helmet design, along with Pink was my least favorite. The Triceratops mouth was thinner and more triangular, the horns popped out more and the visor was more narrow. His chest had one diamond in the front versus have a diamond and two triangle. The back had two diamonds, the gloves and boots have ranger-colored arcs. The black buckles of the
Power Morphers are ranger-colored. Their hostlers were ranger colored
and black trim versus the original white with red trim. His chest coin went from Triceratops to Wolf. We never saw them use the Blade Blasters but they were Ranger-colored.
Black Ranger
To me, the helmet design looks very similar except for the widen-ness and the bigger mouth plate than the original. His chest had one diamond in the front versus have a diamond and two
triangle. The back had two diamonds, the gloves and boots have
ranger-colored arcs. The black buckles of the
Power Morphers are ranger-colored. Their hostlers were ranger colored
and black trim versus the original white with red trim. His chest coin
went from Mammoth (I mean Mastodon) to Frog. Originally the belts had a ranger-color stripe top and bottom, they probably thought it was over-kill and nixed it.
Yellow Ranger
Her chest had one diamond in the front versus have a diamond and two triangle, also her breasts were part of the armor with three lines on each side under the boob. The back had two diamonds, the gloves and boots have ranger-colored arcs. The black buckles of the
Power Morphers are ranger-colored. Their hostlers were ranger colored
and black trim versus the original white with red trim. Her chest coin went from Saber-Tooth Tiger to Bear. I like her helmet design and especially the eye lights. The snout was flatter but more triangular and the eyes were wider. Everything was more protruded.
White Ranger
Instead of a gold belt, he had a white belt. Instead of the Dairanger buckle, he had a Power Morpher, with white buckle around it. His shield had two triangular parts under it, it was more arched, compared to the straight bottom of the original shield. While the original shield shoulder pads were arced and straight, this one was a straight angle. His back shield was also arced on the bottom. He had the same cuffs as he did in the original. Instead of Ranger-colored designs on his boots and wrists, he had gold. The black parts on the top were wider and bigger. His white tiger eyes were more narrow and 'evil' looking. His mouth piece was more boxier. I like the choices but I wish they went with the gold belt because withe the white, I feel it washes the costume out. Also, they switched the Kibaranger tiger symbol for the Falcon. 
Saba
It is hard to tell since he has such a brief and far away appearance. But it looks like his face is boxier. His gold is shiner and seem to have the same basic details, just his face looks more robotic and plastic-y. His snout also doesn't protrude as much as the original.
