Theresa - Light Aqua Top, White Trousers

Theresa from the Summer Riding Camp is a desirable minifigure for LEGO Friends collectors, especially those focused on completing their collection of minidolls. Her light aqua top and white trousers give her a unique, summery look that stands out among other figures. The specific hairpiece in dark red also adds to her appeal.

As part of a retired set, Theresa is no longer in production, increasing her collectibility over time. Mint condition versions, particularly with original accessories, are highly sought after. The fact that she only appears in one set further boosts her desirability.

Theresa's rarity is moderate, as she only appears in the Summer Riding Camp set (3185-1) from 2012. This single appearance limits the overall number of figures available on the secondary market. While not a limited edition or promotional minifigure, her exclusivity to a single, now-retired set contributes to her increasing scarcity.

The investment potential for Theresa is moderate. As a character from the LEGO Friends line, she benefits from the theme's continued popularity and collector base. The retirement of the Summer Riding Camp set means that her value is likely to appreciate over time, especially for those in excellent condition. Keeping an eye on market trends and demand for LEGO Friends minifigures will be crucial in assessing her long-term investment viability.
