The first thing I check is the mirror attached to it, not the drawers, not the legs. A vanity lives or dies by how it makes you look at seven in the morning with bad lighting and worse hair. If the mirror throws shadows under your eyes or gives everything a greenish tint, the prettiest table in the world is not going to save it. I want a mirror that is honest in daylight and still kind under a lamp at night, and that is rarer than it should be.
Now the honest part. A vanity table is a one job piece of furniture, and if you do not have a dedicated spot for getting ready, it is going to turn into the place where mail dies and jewelry tangles into one sad knot. I love mine, but I will tell you straight, if your bedroom is tight on space, a wall mounted mirror and a drawer somewhere else will serve you better than a table that eats floor space just to hold a hairbrush and three half used candles. Small bedrooms and vanity tables do not always get along, and pretending otherwise just means more stubbed toes.
Where it does earn its spot is in a corner with a window nearby, because natural light does more for your makeup and your mood than any ring light ever will. A vanity with a warm wood top or a painted finish in a color with some personality sits beautifully against a plain wall, especially if you let the chair be the loud thing. Emerald velvet stool, plain white vanity, a strip of brass hardware catching the morning light. My mother would call it too much. It is not too much. It is a reason to actually sit down and get ready instead of leaning over a bathroom sink.
What it clashes with is cold, clinical light and a room that is already busy with pattern everywhere. If your bedroom walls are already doing a lot, a vanity with an ornate mirror or a loud finish is going to compete instead of complete. Pick one hero in that corner. Let the vanity be quiet if the walls are loud, or let it be the bold thing if everything else is calm. Mixing two showoffs in one small zone just looks like an argument nobody is winning.
So before you buy one, stand in front of the mirror attached to it in the worst light the shop has, and ask yourself honestly, do I look like myself, or do I look like I need an appointment?
