Prom dresses under $100 at Starlish make it possible to find a real prom night look without stretching your budget — this collection pulls from both short and long styles, in colors spanning purple, blue, black, silver, brown, and dark green.

Styles range from strapless cocktail dresses and bodycon minis to ruffled short gowns and homecoming-style dresses, so staying under $100 doesn't mean picking from a narrow, leftover selection. Several styles include lace appliques, spaghetti straps, or a cowl-neck detail for a bit more polish.

Fabric spans satin, chiffon, and stretch bodycon knits, the same range used across Starlish's pricier collections — the lower price reflects a simpler silhouette or shorter length, not a difference in construction quality.

Every dress in this collection is available in custom sizing at no extra charge, so a tighter budget doesn't mean settling for a standard size chart.
