![[Experiment] Boyfriend Shirt (Oversized Shirt) Test — Recreating 'Covered Yet Suggestive' with Prompts](/tips/boyfriend-shirt-test/A_seed42_0_0000_42.webp)
Conclusion
oversized shirt/boyfriend shirtproduce equivalent output with no difference (oversized shirtis more token-efficient)- Specifying a white dress shirt shifts toward a more formal design
unbuttonedspecification consistently reflects button-opening (chest exposure)- Adding
bare legsslightly increases leg exposure but not dramatically - Bedroom + morning light background is consistently generated across all conditions
What This Article Covers
- Whether
oversized shirt/boyfriend shirtcan generate a boyfriend shirt-style image - Controllability of skin exposure level (button opening, hem length)
- Whether “worn bare-skinned directly” can be expressed with prompts
- Effects of specifying shirt color and design on results

Base Prompt
Setting the scene as a bedroom in the morning wearing a boyfriend shirt.
Condition A: oversized shirt (2 tokens)
The simplest oversized shirt expression.
Observations
An oversized striped shirt (light blue) worn as a single layer. Hem reaches to mid-thigh with bare legs visible. Bedroom + morning light background. The typical boyfriend shirt composition is stably reproduced.
Condition B: boyfriend shirt (2 tokens)
The English expression for “boyfriend shirt.”
Observations
Same oversized shirt look as A. No clear difference between “boyfriend shirt” and “oversized shirt” in output.
Condition C: oversized white dress shirt (4 tokens)
Specifying a white dress shirt concretely.
Observations
White dress shirt generated as specified. Button-down formal shirt design — different from A’s casual shirt.
Condition D: wearing only a shirt + oversized (5 tokens)
Explicitly specifying wearing only a shirt.
Observations
Similar oversized shirt as A. Adding “wearing only” doesn’t significantly change exposure level.
Condition E: unbuttoned oversized shirt (3 tokens)
Specifying the unbuttoned state.
Observations
Shirt with buttons open. Chest to abdomen exposure increases. “unbuttoned” is consistently reflected.
Note: Unbuttoned reliably produces open buttons showing chest to abdomen, making it a central element of the “covered yet suggestive” look. Achieving this level of exposure from a single shirt is useful for prompt design.
Condition F: oversized shirt + bare legs (4 tokens)
Additional specification to emphasize bare legs from under the hem.
Observations
Same composition as A but bare legs are more emphasized. Shirt hem tends slightly shorter with more leg exposure.
Cross Comparison
All Conditions Comparison

A/B/D are nearly equivalent. C leans more formal. unbuttoned (E) shows the largest exposure change.
Note: The boyfriend-shirt look is basically complete with
oversized shirtin 2 tokens, sounbuttonedis the one addition worth making. For a “covered yet suggestive” look,unbuttoned oversized shirtis the most token-efficient minimum configuration.
Key Findings
Keyword Comparison
oversized shirt/boyfriend shirtproduce equivalent output with no difference. Token count is the same so either works- “oversized white dress shirt” shifts to a formal dress shirt style. Can be used to distinguish from casual shirts
Exposure Control
- Adding “wearing only” doesn’t significantly change exposure. The default already produces a sufficiently boyfriend-shirt-like composition
- “unbuttoned” is the most effective keyword for increased exposure. Chest to abdomen exposure is consistently reflected
- Adding “bare legs” slightly increases leg exposure but not dramatically
Background / Situation
- Bedroom + morning light (bedroom, morning light) background is consistently generated across all conditions — background specification is effective
Recommended Prompts
- Basic:
oversized shirt(2 tokens) is sufficient - Chest exposure: Add
unbuttoned oversized shirt - Formal feel: Change to
oversized white dress shirtfor white dress shirt
