I completed Ezarel's outfit after spending roughly 900-1,000 mana, and while it's the best of the four [in my opinion], it gives off the biggest spring/Easter theme I've ever seen. I guess you can count the rose flowercrown and the roses around the bottom of the big dress as "Valentine's," but it's not much. I'm not entirely sure whether it fits Ezarel's style, mainly because it seems too poofy.
Leiftan's outfit seems to reflect him pretty well. The gold for his hair and the white colors for his own clothing, perhaps? Still, it doesn't seem very good for Valentine's Day. It looks like it was made as a bridesmaid's dress, half mixed with getting married because of the veil thing, and then the Phoenix outfit got added into it. Then again, I enjoy the gold bits that it adds to the skirt part. It probably just fits into a spring theme the most.
Oh, boy, Nevra's outfit. What can I say? I love the dress. Like, I really love the rose ruffles and corset thingie [the strings around the waist thing]. It even fits Nevra AND a Valentine's day theme! After that, things start to go bad. The hair and shoes are ok, especially the little things on the side of the shoes. The glove(s)? Big no. It only covers her fingers, so imagine how annoying that is to get on/off. Also, you can't even see her other hand?? The thorny crown? I'd love that for Halloween, not Valentine's Day. Lastly, the one-legged sock. I don't even see a good Halloween use for that one.
And now we have poor Valkyon. This poor boy is going to kiss [I actually don't know that; haven't seen his illustration] a person covered in spikes. SHARP spikes. He's a warrior. He likes strong people. So when he goes to grab you by the hand, arm, waist, or behind the neck for a kiss/hug, he's going to get stuck to death on spikes. The boots and hair look cool, but once again--for Halloween. If we're pushing the warrior theme so much, give him something similar to the Sword and Roses outfit! At least it's not frozen ice spikes.
I usually love Valentine's Day because of the outfit designs. This year? Not so much. I've never gone for the companion, but the gold only option bothers me. However, if we got gold from bindles [which is how I get mine] it's possible to get it. The outfits were just not Valentines. Two could maybe scrape by, but not the others.
It's super expensive, and there's few justified reasons why you've got to pay around 1,000 mana [or more, depending on your luck] for one outfit.
