I would hope, when approached with a situation where one or both sides can’t afford to make a chasunah according to basic community minimum standards, will recognize it as a perfectly valid form of hachnosas kallah.
If:
1: Minimum community standards are minimalistic, and
2: There is oversight (both by Rabbonim and lay leaders) that the family is not using Tzedakah funds to go over that standard, either directly or indirectly
3: The standards are holistic, and cover things like apartment, jewelery, gowns/suits, furniture, etc., not just the actual wedding.
Then I would vote for not only valid (one can argue the Custom Shaitel is valid), but also appropriate. (it does not change the Halachos of Kedimah, though).
