Edinburgh-er & Tatties suits anyone after a warm, low-key nude rather than a true beige or true pink — it reads sandier than either, which flatters a range of skin tones without leaning too pink or too grey.

It's a straightforward at-home option since Infinite Shine doesn't need a lamp, and it's equally at home in a salon service since OPI sells the line through professional channels as well as retail.

This shade fills a specific gap: a warm sand tone that isn't quite beige and isn't quite pink, which is harder to find than either extreme. It comes from OPI's Scotland-themed collection, though the color itself wears well outside of any seasonal or thematic tie-in.

It carries the same long-wear system as the rest of Infinite Shine, so the appeal isn't unique mechanics — it's a specific, wearable neutral that more common beige and blush shades don't quite hit.

Infinite Shine's three steps apply the same way regardless of shade:

• Start with clean, dry, lightly buffed nails.
• Apply one coat of Infinite Shine Primer.
• Brush on two thin coats of Edinburgh-er & Tatties, capping the free edge each time.
• Finish with one coat of Infinite Shine Gloss, capping the edge again.
• Remove with regular acetone remover; no soaking required.

• Pro: Warm sandy-nude tone works across a wide range of skin tones without reading too pink or too ashy.
• Pro: Crème finish means full, even coverage in two coats with no shimmer particles to manage.
• Con: As an older shade from OPI's Scotland collection, it has shown up marked discontinued at some professional distributors, so restocking may be less predictable than current-season shades.
• Con: Full 11-day wear depends on using the Infinite Shine Primer and Gloss alongside the color, not the lacquer alone.
